SOLUTION: This is kind of a long one (three different parts) but I appreciate the help! Multiply and simplify. a) {{{( sqrt( x^3 ) )( sqrt( x^5 ) )}}} b) {{{ sqrt ( x )(3- sqrt ( x ))}}

Question 291380: This is kind of a long one (three different parts) but I appreciate the help!
Multiply and simplify.
a) %28+sqrt%28+x%5E3+%29+%29%28+sqrt%28+x%5E5+%29+%29
b) +sqrt+%28+x+%29%283-+sqrt+%28+x+%29%29
c) %282%2B+sqrt+%28+6+%29+%29%283%2B+sqrt+%28+6+%29+%29

You can put this solution on YOUR website!
a) %28+sqrt%28+x%5E3+%29+%29%28+sqrt%28+x%5E5+%29+%29 = %28+sqrt%28x%5E3%2Ax%5E5+%29+%29 = sqrt%28x%5E8%29 = x^4
:
b) +sqrt+%28+x+%29%283-+sqrt+%28+x+%29%29 = 3sqrt%28x%29+-+x
:
c) %282%2B+sqrt+%28+6+%29+%29%283%2B+sqrt+%28+6+%29+%29
FOIL
6+%2B+2sqrt%286%29+%2B+3sqrt%286%29+%2B+6 = 6+%2B+6+%2B+5sqrt%286%29 = 12+%2B+5sqrt%286%29
