Question

alguem me ajuda com as potencias..

1- (-10a³)² =

2- (2x²)⁵ =

3- (-3.b⁵c⁴)² =
      7
      

Answer 1

Eleva o n° e multiplica os expoentes

1)

$(-10a^3)^2=(-10)^2.a^6=100a^6$

$2) \\ (2x^2)^5=2^5.x^1^0=32x^1^0$

$3) \\ (- \frac{3}{7} b^5c^4)^2=(- \frac{3}{7} )^2.b^1^0.c^8= \frac{9}{49} b^1^0c^8$
