Question

Write the expression without a radical.

Answer 1

\[\sqrt[4]{16a^6b^4}\]

Answer 2

I know 16 will be 2, b will be b, but what about a^6..?

Answer 3

remember you can change root to exponent like \[\huge\ \sqrt{x} = x^{\frac{ 1 }{ 2 }}\]

Answer 4

so \[\huge\sqrt[4]{a^6} = a^?\]
another example is \[\huge\rm\sqrt[m]{x^n} = x^{\frac{ n }{ m }}\]

Answer 5

a^6/4?
