How do I solve these math problems?

x^(5/4) times x^(15/4) (assume all bases are positive)

(64/9)^(1/2)

Both problems say to simplify them. Thank you so much.

    When you multiply terms with the same base, simply add the exponents:

    x^(5/4) x^(15/4)

    x^(5/4 + 15/4)

    x^(20/4)

    x^5

    The second is simple: distribute the exponent to each of the included terms:

    (64/9)^(1/2)

    64^(1/2) / 9^(1/2)

    8 / 3

    First one is x^(20/4) second one could be 32/9 but not sure.

    Not Quite sure, but can you try substituting a number for x?
