i am clueless about this:
(#1)What expression raised to the fourth power is 81x^12y^8z^16?
(#2)Simplify each of the following expressions. Write your answers with positive exponents only.
(x^2)^3(x^2) divided by (x^2)^4
#1 answer (3x^3)(y^2)(z^4)
because 3^4=81
(x^3)^4=x^12 multiply powers
(y^2)^4=y^8 "
(z^4)^4=z^16 "
#2answer is 1
because (x^2)^3=x^6 mulityply powers
(x^6)(x^2)=x^8 add powers
(x^2)^4=x^8 multiply powers
(x^8)/(x^8)= x^0 subtract powers and any number to the power of zero is 1
(x^8)/(x
thank you for explaining them to me.
