Cuocitis vivvbivi it such in
((3x^2)^a - (4y^a)(z^3a))^2
First, expand.
((3x^2)^a - (4y^a)(z^3a)) ((3x^2)^a - (4y^a)(z^3a))
Combine
3^(2a) - x^(4a) - 8 * 3^(2a)x^(2a)y^(a)z^(3a) + 16y^(3a)z^(6a)
hope this helps
1/3^5
When multiplying exponents you just add them. X^a x X^b = X^a+b
If you have a negative exponent, you flip it to be the denominator (if originally numerator) or numerator (if originally denominator.
So, 3^-5 = 1/3^5
