Math is absolutely my worst subject and I am now struggling to learn math all over again in preparation for my GRE. Can you please help me solve and explain the two following problems?

(√300) ∕ (√12)

(√5) (√2) - √90

Thank you (Rofl)

Thanks, how about the second problem. The book answer is -2√10 and I can't figure out how they came up with that since you can only add/subtract when numbers inside square root are identical and have no idea of how to break it down.
