Question

3) Calcule as potencias do números Racionais abaixo

b)(+ 7) ^ 4 =;
c)( 6 7 )^ 2 =
d) (1/3) ^ 2 × (1/2) =
e) (1,5)^ 4 =​

Answer 1

Explicação passo-a-passo:

$b) {7}^{4} = 2404$

$c)(67) {}^{2} = 4489$

$d)( \dfrac{1}{3} ) {}^{2} \times \dfrac{1}{2} = \dfrac{1}{9} \times \dfrac{1}{2} = \dfrac{1}{18}$

$e)(1.5) {}^{4} = 5.0625$
