What about these types of radicals?
I have only about fifty more to do at the moment and am struggling on a few more.
First problem not sure I really get this type of one
Use rational exponents to simplify each expression.
Second is to simplify the indicated operation.
√5x^2 * √10y
Third is:solving this radical equation:
√x+9 - √x-7=2
Fourth is:perform indicated operation. Write in the form of a + bi
(5-3i) - (6-9i)
would I do the foil on this where 30-18i+18i okay no that ones is wrong.
Question on my second problem
The problem is
√5x^2 * √ 10y
The book is saying 3
√ 50x^2y as an answer but I see you have 1/3 in there. Where does that come in? I think I am more confused??
