$a) {9}^{ \frac{3}{2} } \\ b)8 {}^{ \frac{4}{3} } \\ c)64 {}^{ \frac{2}{3} } \\ d) {81}^{ - 0.25} \\ e)( 16 {}^{ \frac{5}{4} } ) {}^{ \frac{2}{5} }$

Answer 1

Boa tarde

a) 9^(3/2) = 3^3 = 27 

b) 8^(4/3) = 2^4 = 16 

c) 64^(2/3) =  4^2 = 16 

d) 81^(-0.25) = (1/81)^/1/4) = 1/3 

e) (16^(5/4)^(2/5) = 16^(1/2) = 4
