Question

find the value of the following :
i ). (x²)⁵ (x-³)²
ii). (27)⅔
iii). (a³)⁴ ÷ (a⁵)²​

Answer 1

Step-by-step explanation:

i ) (x²)⁵ (x-³)²

= (x¹⁰) (x-⁶)

= x¹⁰+(-⁶)

= x¹⁰-⁶

= x⁴

ii) (27)⅔

= (3³)²/³

= 3³*²/³

= 3²

iii) (a³)⁴ ÷ (a⁵)²

= a¹²÷a¹⁰

= a¹²-¹⁰

= a²

using formula (x^m)^n = x^(mn)

x^m*x^n = x^(m+n)

(x^m)÷(x^n) = x^(m-n)
