5. Power of a Power (63)4 = 63•63•63•63 = 612 (x5)3 = x5•x5•x5 = x15
This property is used to write an exponential expression as a single power of the base.
(63)4
= 63•63•63•63
= 612
(x5)3
= x5•x5•x5
= x15
When you have an exponent raised to an exponent, multiply the exponents!

7. Power of a Product (xy)3 (2x)5 = x3y3 = 25 ∙ x5 = 32x5 (xyz)4
Power of a Product – Distribute the exponent on the outside of the parentheses to all of the terms inside of the parentheses.
(xy)3 (2x)5
= x3y3
= 25 ∙ x5
= 32x5
(xyz)4
= x4 y4 z4

8. Power of a Product (x3y2)3 (3x2)4 = x9y6 = 34 ∙ x8 = 81x8 (3xy)2
More examples…
(x3y2)3 (3x2)4
= x9y6
= 34 ∙ x8
= 81x8
(3xy)2
= 32 ∙ x2 ∙ y2
= 9x2y2
