Question 44107: I am so confused with these problems....
What expression raised to the fouth power is 81x (12 to the power)y (8 to the power) z (16 to the power).
All number except the 81 are exponents.

Let us write it this way...looking for n such that
n^4 = 81(x^12)(y^8)(z^16)
well we need to raise both sides to the 1/4 power, so that
n = ±3(x^3)(y^2)(z^4)
