Question

Alguém me explica passo a passo?

Answer 1

a= (1/25)^1/2·25^3/2 / 2(1/1000)^1/3
a= √1/25 · √25³ / 2·(∛1/1000)
a= 1/5 · √(5³)² / 2·(1/10)
a= 1/5· √5⁶/ 2/10
a= 1/5·√5²·5²·5²/ 1/5
a= 1/5·125/ 1/5 (simplifica os dois 1/5)
a= 125


b= 10/3·[3^-1 -(-3)^-1]^-1
b= 10/3·[1/3+1/3]^-1
b= 10/3· [2/3]^-1
b= 10/3·3/2
b= 30/6
b= 5

a/b= 125/5
a/b= 25
