Question

IF YOU KNOW ALONE SAY THE ANSWER​

Answer 1

Step-by-step explanation:

$\frac{1}{3}^{-1} = 3$

1. $\frac{8}{5}^{-6}\times\frac{-5}{8}^{-2}$

⇨$\frac{8}{5}^{-6}\times\frac{8}{5}^{2}$

⇨$\frac{8^-6×8^2}{5^-6×5^2}$

⇨$\frac{8^-4}{5^-4}$

⇨$\frac{8}{5}^{-4}$

⇨$\frac{5}{8}^{4}$

⇨$\frac{625}{4096}$

2.($\frac{1}{2}^{3} - \frac{1}{4}^{3}$)${2}^{3}$

⇨${2}^{3}$ $\frac{1}{2^3}$ - ${2}^{3}$ $\frac{1}{2^6}$

⇨1 - $\frac{1}{2^3}$

⇨1 - $\frac{1}{8}$

⇨$\frac{8-1}{8}$

⇨$\frac{7}{8}$
