Question

If a and b are positive integers and [a^(1/2)]x[b^(1/3)]=432.... What is the value of ab?

Answer 1

I've gotten to: √a 3√b = 6√432

(those are cube roots and such)

Answer 2

resolve 432 into its prime factors

Answer 3

432=2*2*2*2*3*3*3

Answer 4

there that was fast
you get 2^4*3^3 or more conveniently 4^2*3^3
so a=4 and b=3

Answer 5

wait scratch that

Answer 6

no that's right! thanks!

Answer 7

ok whatever

Answer 8

Lolol
