Can you please explain to me how I can solve these problems?

Question

(3^ square root of3) ^square root of 3

(x^ square root of 2) ^square root of 7

5^(2)(square root of 3) • 5^(4)(square root of 3)

x^(3)(pi) / x^(pi)

Answer 1

1. (3^sqrt3)^sqrt3 = 3^3 = 27.

2. (X^sqrt2)sqrt7 = X^sqrt(2*7) = X^sqrt14.

3. 5^2sqrt3 * 5^4sqrt3 = 5^6sqrt3.

4. X^3pi / X^pi = X^2pi.
