text: having a problem simplifying square roots? sqrt (3w^3 u^4)   sqrt (15w^2u)  when i try to put this into the algebrator, i cannot seem to simplify how do i dothis? sqrt (3w^3 u^4) sqrt (15w^2u) = sqrt {(3w^3 u^4)(15w^2u)} = sqrt( 45 x (uw)^5} = sqrt{5 x 3^2 x (uw)^4 x uw} = 3 x (uw)^2 x sqrt(5uw)  th
