im kinda confused, i have to convert an exponent to exponential form if its in radical form or radical form if its it exponetion, the problem is: 16^(5/4) =32
ps im sorry about the wierd symbols, i dont know how to make it look nice like it does in my math book

What weird symbols?
Anyway, this one's just using the definition of exponentiation for rational exponents: a^(p/q) = (root (a, p))^q, where root (a, p) is the pth root of a. So for this problem, 16^(5/4) = (∜16)⁵.

16^(5/4) means ∜(16⁵) or equivalently (∜16)⁵
You can see that the second one is much easier to solve.
The fourth root of 16 is 2. And 2 to the fifth power is 32.
Off the top of my head I do not know what 16 to the fifth power is, so I would have to grab a calculator.
