5) Calcule o valor da expressão$\frac{16^{-0,75}+\sqrt[5]{0,00243}}{\frac{2}{3}+4,333...}$

Answer 1

Resposta:

Explicação passo a passo:

16^-0,75=

0,75=75/100=3/4

16^-3/4=

(2^4)^-3/4=

2^-12/4=

2^-3=

1/8

5V0,00243=

(0,00243)^1/5=

(3/10^5)1/5=

(3/10)^5/5=

3/10^1=

3/10

4,3333...=

4+3/9=

36/9+3/9=

39/9

16^-0,75+5V0,00243/2/3+4,333...=

1/8+3/10/2/3+39/9=

5/40+12/6/9+39/9=

17/40/45/9=

17/40/5

17/40.1/5

17/200=

0,085
