1/x^3 = 216 third root(1)/third root(x^-3) = third root(216) third root(1)/x = third root(216) 1/x = third root(216) 1/third root(216) = x i think that is how you do it please check again or confirm with others.
tan(255) = tan(180+75) = tan 75 = tan(30 + 45) = (tan30+tan45)/ (1-tan30tan45) You can finish the rest. Note: tan(180+75) = (tan180+tan75)/ (1-tan180tan75) = (0+ tan75)/(1-0) =tan 75 = tan (30+45) not my answer but credits to: mlam18
