Answer 1

Step-by-step explanation:

Given:-

176^2-24^2

To find:-

Evaluate 176^2-24^2 by using Identity?

Solution:-

Given numerical expression is 176^2-24^2

It is in the form of a^2-b^2

Where a = 176 and b=24

We know that

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

=> 176^2-24^2

=> (176+24)(176-24)

=> (200)(152)

=> 30400

Answer:-

The value of 176^2-24^2 is 30,400

Used Identity:-

• (a+b)(a-b) = a^2-b^2

Answer 2

Answer:

The identity is (a^2-b^2)

a^2-2×(a+b)+b^2

Step-by-step explanation:

176^2-24^2

176^2-2×(176+24)+24^2

30976-400+576

31,152
