Given:

Expression: [(91 ÷ 7) × {(64 ÷ 4) + (17 ÷ 6) × (8 - 2)}]

Formula Used:

Order of operations (BODMAS): Solve inside brackets first, then division/multiplication, and finally addition/subtraction.

Calculation:

⇒ [(91 ÷ 7) × {(64 ÷ 4) + (17 ÷ 6) × (8 - 2)}]

⇒ (13) × {(16) + (17 ÷ 6) × (6)}

⇒ (13) × {16 + (17 × 6 ÷ 6)}

⇒ (13) × {16 + 17}

⇒ 13 × 33

⇒ 429

∴ The value of [(91 ÷ 7) × {(64 ÷ 4) + (17 ÷ 6) × (8 - 2)}] is 429.

Given:

The expression to solve is: 44 × (84 ÷ 7) ÷ 2 - {3 × 10 + 10 - (6 - 3) ÷ 3}

Calculation:

44 × (84 ÷ 7) ÷ 2 - {3 × 10 + 10 - (6 - 3) ÷ 3}

44 × 12 ÷ 2 - {3 × 10 + 10 - 3 ÷ 3}

44 × 6 - {30 + 10 - 1}

264 - 39 = 225

The final value of the expression is 225.

Given:

10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?

Formula Used:

Division of fractions: a ÷ (b/c) = a × (c/b)

Order of operations (BODMAS): Brackets → Orders (powers, roots) → Division → Multiplication → Addition → Subtraction

Calculation:

10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?

⇒ 10620 ÷ [(3/4) (138) - 60/4)] = ?

⇒ 10620 ÷ [414/4 - 60/4] = ?

⇒ 10620 ÷ 354/4 = ?

⇒ 10620 × 4/354 = ?

⇒ 120

∴ Option 3 is the correct answer.

Given:

(828/4) × 3 - (8 × (6/24) × 10) + (105/35) - 15 

Concept used: 

Follow the BODMAS rule according to the table given below:

Calculation:

⇒ (828/4) × 3 - (8 × (6/24) × 10) + (105/35) - 15 

⇒ (207) × 3 - (8 × (1/4) × 10) + (3) - 15 

⇒ 207 × 3 - (2 × 10) + 3 - 15 

⇒ 621 - 20 + 3 - 15 

⇒ 621 - 17 - 15 

⇒ 621 - 32

⇒ 589

∴ (828/4) × 3 - (8 × (6/24) × 10) + (105/35) - 15 = 589

Given Equation:

Concept Used:

The concept of BODMAS is used

B = Bracket

O = Of

D = Division

M = Multiplication

A =Addition

S = Subtraction

Calculations:

First we have to solve brackets

⇒ 

⇒ 

⇒ 

⇒ 

⇒ 

⇒ 

⇒ x(x - 1) + 16(x - 1) = 0

⇒ (x - 1)( x + 16) = 0

The value of x is 

⇒ x = +1 or -16

Now, The difference between the two values of x is 

⇒ Difference = 1 - (-16) = 1 + 16 = 17

⇒ Hence, The difference between the two values of x is 17

Solution:

We have to follow the BODMAS rule

Calculation:

⇒ ? = 3²

∴ ? = 9

Concept used:

ax × ay = ax + y

ax ÷ ay = ax - y

Calculation:

(4 × 4)³ ÷ (512 ÷ 8)⁴ × (32 × 8)⁴ = (2 × 2)^{(? + 4)}

⇒ 4⁶ ÷ (64)⁴ × 256⁴ = (4)^{(? + 4)}

⇒ 4⁶ ÷ (4³)⁴ × (4⁴)⁴ = (4)^{(? + 4)}

⇒ 4^{(6 + 16 - 12)} = (4)^{(? + 4)}

⇒ 4¹⁰ = (4)^{(? + 4)}

So, ? + 4 = 10

⇒ ? = 10 - 4

∴ ? = 6

Shortcut Trick Formula:

(a+b)2 - 4ab = (a-b)2

Calculation:

(957 + 932)2 - 4 × 957 × 932

= (957 - 932)2

= 252 = 625

Alternate Method GIVEN:

 - 4 × 957 × 932.

FORMULA USED:

BODMAS 

CALCULATION :

⇒  - 4 × 957 × 932 

⇒ 3568321 - 4 × 957 × 932 

⇒ 3568321 - 3567696  =  625 

∴ The value is 625.

Follow BODMAS (Brackets, Of, Division, Multiplication, Addition, Subtraction) rule to solve this question, as per the order given below,

Step-1- Parts of an equation enclosed in 'Brackets' must be solved inside the bracket first,

Step-2-  Then any mathematical 'Of' or 'Exponent' must be solved,

Step-3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

1251/3 × 271/3 × 1254/3 = 15 × 5?

⇒ 5 × 3 × 5⁴ = 15× 5^x

⇒ 15 × 5 ⁴ = 15× 5^x

⇒ x = 4

Hence option 4 is correct.

Concept used:

Follow BODMAS rule to solve this question, as per the order given below:

⇒ 8 = (?)³/(2)³

⇒ (2)³ = (?)³/(2)³

⇒ 2³ × 2³ = (?)³

⇒ 4³ = (?)³

⇒ ? = 4

∴ The value of ? is 4.

Concept used:

Calculation:

196² × 56 ÷ 14⁵ × 1021 

⇒ (14²)² × (56/14⁵) × 1021 

⇒ [14⁴ × (56/145)] × 1021 

⇒ (56/14) × 1021 

⇒ 4 × 1021 = 4084

∴ The answer will be 4084.

Using BODMAS rule:

⇒ 63 - (- 3)(- 2 - 8 - 4) ÷ [3 {5 + (- 2)(- 1)}]

⇒ 63 - (- 3)(- 2 - 8 - 4) ÷ [3 {5 + 2}]

⇒ 63 - (42) ÷ 21

⇒ 61

1132.757 – 2315.996 – 1753.829 + 2 × 2846.639

= 1133 – 2316 – 1754 + 5694

= (1133 + 5694) – (2316 + 1754 )

= 6827 – 4070

= 2757

Concept used:

Calculation:

⇒ 56 ÷ [(1/3){15 + 12 - (9 + 6 - 12)}]

⇒ 56 ÷ [(1/3){15 + 12 - (15 - 12)}]

⇒ 56 ÷ [(1/3){15 + 12 - 3}]

⇒ 56 ÷ [(1/3){27 - 3}]

⇒ 56 ÷ [(1/3)(24)]

⇒ 56 ÷ 8

⇒ 7 

∴ ? = 7

Important Points

If in any simplification problem there is (  ̅  ) bar sign above any operation then we should perform the operation at the beginning, whatever the operation is. Then we will follow the chart given above.
