Question 588284: Please help? Multiply, and simplify: +sqrt%28+8x%5E5+%29%2A+sqrt%28+3x+%29
So far I have, +sqrt+%28%288x%5E5%29%29+%283x%29+ then, +sqrt+%2824x%5E6%29+
I don't where to go from there, or even If what I have so far correct.

Hello,
Let's approach this from another way:
+sqrt%28+8x%5E5+%29%2A+sqrt%28+3x+%29 this can be written as:
( 8x^5 )^1/2 * ( 3x )^1/2
Now we can write it as:
(8x^5)(3x) because we add the exponents 1/2+1/2=1
Now this can be written as:
24x^6
Make sense?
