Square root 6a    -  4square root 54a   -   4 square root 216a

simplify by combining like radical terms. Assume all veriables and radicands represent nonnegative numbers

anonymous · Answer

sqrt(6a) -4*sqrt(54a) -4*sqrt(216a)

54=9*6 & 9=3^2, so sqrt(54)=3*sqr(6)

216=36*6 & 36=6^2, so sqrt(216)=6*sqrt(6)

yu hav sqrt(6a)-12*sqrt(6a) -24*sqrt(6a)

-35*sqrt(61)

@glea finaly is -35sqrt6a and not sqrt61 

ok ? ATTENTION !!!
