Question

evaluate using suitable identity 48*52

Answer 1

Heya

48 × 52

We use this identity

(a+b) (a-b) = a^2 - b^2

48 × 52

(50-2) (50+2)

= (50)^2 - (2)^2

= 2,500 - 4

= 2,496





Thanks

Answer 2

The value of 48 × 52 is 2496

Given :

The expression 48 × 52

To find :

The value using suitable identity

Formula :

a² - b² = ( a + b ) ( a - b )

Solution :

Step 1 of 2 :

Write down the given expression

The expression 48 × 52

Step 2 of 2 :

Find the value using suitable identity

We use the identity a² - b² = ( a + b ) ( a - b )

Thus we get

$\sf 48 \times 52$

$\sf = (50 - 2) \times (50 + 2)$

$\sf = (50 + 2) \times (50 - 2)$

$\sf = {50}^{2} - {2}^{2}$

$\sf = 2500 - 4$

$\sf = 2496$
