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]
