Answer:

Step-by-step explanation:

To find ---> Value of given expression

Solution--->

(1) please refer the attachment .

2) First we apply two laws of exponent which are as follows

a) ( xᵐ )ⁿ = xᵐⁿ

b) ( x / y )ᵐ = xᵐ / yᵐ

3) In third step we apply an identity as follows,

( a + b ) ( a - b ) = a² - b²

4) In fifth step we apply a law of exponent as follows,

aᵐ aⁿ = aᵐ⁺ⁿ

Additional information----->

1) aᵐ ÷ aⁿ = aᵐ⁻ⁿ

2) a⁰ = 1

3) ( a b )ᵐ = aᵐ aⁿ

4) ( a³ + b³ ) = ( a + b ) ( a² + b² - ab )

5) ( a³ - b³ ) = ( a - b ) ( a² + b² + ab )

6) ( a + b )³ = a³ + b³ + 3ab ( a + b )

7) ( a - b )³ = a³ - b³ - 3ab ( a - b )

8) ( a + b )² = a² + b² + 2ab

9 ) ( a - b )² = a² + b² - 2ab
