Simplify the expression 3√27x^6y^4 Show your work.

Step-by-step explanation:

By applying exponet rules.

cube root of 27 = 3

(x^6)^1/3 = x^6x1/3 = x^2

(y^4)^1/3 = y^4x1/3 = y^4/3

Could be wrong, but it's my shot at it.

Edit this solution is correct but you can take in one step further.

replace y^4/3 with y

47 - 90 = 43

43 - 180 = x

x = 137

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
