Question

(6) Find the value of 4th root 625 raised to the power of-2​

Answer 1

Answer:

$\frac{1}{25}$

Step-by-step explanation:

4th root of 625 is equal to performing two square roots on 625

ie.

1st square root: √625 = 25

2nd square root: √25 = 5

4th root of 625 = 5

and we all know:

${5}^{ - 2} = \frac{1}{25}$

Answer 2

Answer:

0.04

$\sqrt[4]{ {625}^{ - 2} }$

$1 \div \sqrt[4]{ {625}^{2} }$

$1 \div \sqrt[4]{390625}$

$\sqrt[4]{0.000000256}$

$\sqrt{0.0016}$

$0.04$
