Question

Simplify the expression: 4 times Start Root 18 End Root plus 5 times Start Root 32 End Root

Answer 1

You have entire radicals that need to be turned into mixed radicals (then you have to collect like terms : )
4 √ 18 x √18 + 5 √ 32
=4√(9x2) + √2 (9x2) + 5√(16x2)
= 4x3√2 + 3√2 + 5x4√2
= 12√22 + 3√2 + 20√2
= 35√2

Answer 2

Sorry... my answer above got way to zellus with the html language (I mis inputted your question). Here is the correct solution : )
4 √ 18 + 5 √ 32
=4√(9x2) + 5√(16x2)
= 4x3√2 + 5x4√2
= 12√2 + 20√2
= 32√2
