Help please.. -2√(6k^3) 3√(21k^2) Simplify
exactly what is there ? -2sqrt(6k^3) * 3sqrt(21k^2) = ?
hmm well thats stupid.. lol my teacher wrote that down and told me to simplify it, but if its already simplified, why have that as a question... Thanks!
so how i have wrote above is right ?
hope is correct so than you need calculi,simplifie first what is inside squareroot ok ?
first there is sqrt(6k^3) = can you continue it ?
you dont like cooperat anything ?
sorry but i dont think you can even simplify sqrt(6k^3), at least i dont think..
why ? you can rewriting it like sqrt(6*k^2 *k) =
hope you know that sqrtk^2 =k yes ? than this mean that will be equal ksqrt(6k) do you understand it why ?
