Question

The fifth root of x to the fourth power times the fifth root of x to the fourth power

Answer 1

Remember
(√a)(√b)=√(ab)
and
$(x^m)(x^n)=x^{m+n}$
so

$( \sqrt[5]{x^4})( \sqrt[5]{x^4} )$=
$\sqrt[5]{(x^4)(x^4)}$
4+4=8
$\sqrt[5]{x^8}$=
$( \sqrt[5]{x^5})( \sqrt[5]{x^3} )$=
$x\sqrt[5]{x^3}$

Answer 2

5th root of x to the 4th times 5th root of x to the 4th = 5th root of x to the 8th
Reduces to x times 5th root of x to the 3rd
