Question

d) 0,16^1-2 – 0,027^1-3​

Answer 1

Explicação passo-a-passo:

Potência :

$\mathtt{ (0,16)^{1-2} - (0,027)^{1-3} }$

$\mathtt{(0,16)^{-1} - (0,027)^{-2} }$

$\mathtt{ \Big( \dfrac{4}{25} \Big)^{-1} - \Big( \dfrac{ 27 }{ 1000 } \Big)^{-2} }$

$\mathtt{ \dfrac{25}{4} - \Big( \dfrac{1000}{27} \Big)^2 }$

$\mathtt{ \dfrac{18225 - 4000000}{2916} ~=~ - \dfrac{3981775}{2916} }$

Answer 2

Oie, Td Bom?!

$0,16 {}^{1 - 2} - 0,027 {}^{1 - 3}$

$( \frac{4}{25} ) {}^{ - 1} - ( \frac{27}{1000} ) {}^{ - 2}$

$\frac{25}{4} - ( \frac{27}{1000} ) {}^{2}$

$\frac{18225 - 4000000}{2916}$

$\frac{ - 3981775}{2916}$

$- \frac{3981775}{2916}$
