do we have to simplify?

OpenStudy (anonymous):

yes and leave in radical form

OpenStudy (acxbox22):

okay so lets start by simplifying the 45 from the radical

OpenStudy (acxbox22):

the factors of 45 are 9 and 5 so since 9 is a square number we can factor out a 3 from the radical leaving the 5 in the radical
