Answer 2

Answer:

The missing number = 10444.5

Step-by-step explanation:

Given expression is

[81 x 64 ÷ (4.5)] × 18 = (?) 2- 153

To find,

The missing number in the expression

Recall the concept:

BODMAS Rule:

BODMAS Rule is states the order in which we have to perform operations if multiple operations are present in an expression

As per the rule, the operations Brackets, Order, division, multiplication, addition and subtraction

Solution:

Let 'x' be the missing number

The the expression becomes,

[81 x 64 ÷ (4.5)] × 18 = (x) 2- 153 --------------(1)

First let us the perform the operation in the bracket,

[81 x 64 ÷ (4.5)] = $\frac{81X64}{4.5}$

= $\frac{5184}{4.5}$

= 1152

Then the expression (1) becomes

1152 × 18 = (x) 2- 153

20736 = 2x -153

2x = 20736  + 153

= 20889

x = $\frac{20889}{2}$

= 10444.5

∴ The missing number = 10444.5
