simplify the expression; write without using negative exponents. Assume all numbers are positive

(b^1/2 X a^-5/3)^2

1/2^2 = .25 so 1/4 so b^1/4 and 5/3^2=2.77 so is it b^1/4 a^2.77

  • math - , Sunday, July 4, 2010 at 6:46pm

    (a^b)^c = a^(bc)
    and
    1/2 * 2 = 1 not .25

    (b^1/2 X a^-5/3)^2

    b^1 a^-10/3 = b/ a^(10/3)

    b/a^10/3

    no.

    (bn)m = nmn
    and...

    a-m= 1/am
