Question 161814: This isn't a very complicated radical question, but I don't understand it in any case.
√5 * √5
Is the answer just 5? or √5?
√5 * √10 Does this equal 3√5?
I realize that isnt one question but they're very short.
Thank you for your help.

The definition of sqrt%28x%29 is that x=sqrt%28x%29%2Asqrt%28x%29, so yes,
sqrt%285%29%2Asqrt%285%29=sqrt%2825%29=5
.

.
sqrt%285%29%2Asqrt%2810%29=sqrt%2850%29
sqrt%285%29%2Asqrt%2810%29=sqrt%2825%2A2%29
sqrt%285%29%2Asqrt%2810%29=sqrt%2825%29%2Asqrt%282%29
sqrt%285%29%2Asqrt%2810%29=5%2Asqrt%282%29
