Answer:

For re-expressing the number, we first convert the decimal number 0.2 to a fractional number:

[tex]z^{1/5}= \sqrt[5]{z}[/tex]

Step-by-step explanation:

For re-expressing the number, we first convert the decimal number 0.2 to a fractional number:

n= 0.2  

10n=2

n=2/10=1/5

Therefore we have

[tex] z^{0.2} = z^{1/5} [/tex]

Then as we know that the denominator of fractional exponents can be expressed as a root:

[tex] z^{1/5} = \sqrt[5]{z}[/tex]
