Question

how to convert a radical into a number with an exponet?

Answer 1

\[\sqrt[c]{a^{b}}=a^\frac{ b }{ c }\]
take the number under the radical sign (a) with power b if applicable, and root c. keep the a as the base, raise it to the exponent with b as the numerator and c as the denominator.

Answer 2

should probably elaborate a bit - if you don't see a power b assume the power is 1 (b = 1). by default, the radical sign is a square root with c = 2 if no other value is given.

Answer 3

perfect thanks!
