Question

I am asking for help here...... It says write a expression in radical notation.... 625-1/4

Answer 1

-1/4 is the exponent

Answer 2

\[\frac{1}{\sqrt[4]{625}}\]

Answer 3

In general:

\[y^{-x} = \frac{1}{y^{x}}\]

And:

\[y^{\frac{1}{x}} = \sqrt[x]{y}\]

Answer 4

Hey Sabrena, did you notice that 625 = 5^4?...this means that after doing the chore of writing the number in radical notation, as has been done above, you can simplify it to a really simple number!
