Question

1) 0,36 ^ 1/2
2) 0,25 ^ -05
3) 081 ^ -0,25

Answer 1

$1) \ (0,36)^{\frac{1}{2}}=\sqrt{0,36}=\frac{\sqrt{36}}{\sqrt{100}}=\frac{6}{10}=o,6\\ \\ 2) \ (0,25)^{-0,5}=\frac{1}{(0,25)^{0,5}}=\frac{1}{\sqrt{0,25}}=\frac{1}{0,5}=2\\ \\ 3) \ (0,81)^{-0,25}=\frac{1}{(0,81)^{0,25}}=\frac{1}{ \sqrt[4]{0,81} }=\frac{1}{0,3}=3,3333...$
