Need math help… 6√5 x √5 (could you please explain how to do it)?
6√5 x √5 We multiply together the two radicals. Make sure that the index of the radicals are the same, which is the case here. 6 √25 5(5) 25 answer 3√27 x √ 3. 3√81 3(9) 27 answer The rule is that when multiplying two or more radicals with the same index, simply multiply the radicands together and write the product under one radical symbol. Then simplify the resulting radical if possible. You can not multiply, say, 6 by √5 and get √30. This is wrong. However, there is a way to do this by first transforming 6 to its equivalent radical— √6^2 or √36. Here you can multiply √36 by √5 to get √180. But then if you simplify this you get back to 6√5. Hope this helps.
