Question

Simplifique:
a)(7^2)^3/(7^3)2

b) (3.5^2)^3/(3^2.5)2

Answer 1

a) 7^6 / 7^6 = 7° = 1 resposta.

b) 3³.5^6 / 3⁴.5² =

3-¹ 5⁴ → Resposta.

Answer 2

a
( 7² )³ /  ( 7³ )²  =   7⁶ / 7⁶  = 7 ⁶⁻⁶  = 7⁰  = 1 ****

b

(  3¹ * 5² )³ / ( 3² * 5¹)² =  ( 3³  * 5⁶ ) / ( 3⁴ * 5² ) = ( 3 )³⁻⁴ * ( 5 )⁶⁻² = ( 3⁻¹ . 5⁴ )
= ( 1/3)¹ * 625   =  625/3  ***
