Hey Elizabeth :) Is this what your problem looks like? $$\large\rm \left(2z^4\right)^3$$ We need to simplify?

2. anonymous

Yes :)

|dw:1443121780200:dw|When we have an exponent being applied to a group like this, it needs to be applied to everything in the group.

To deal with the z, apply another rule of exponents:$\large\rm \color{orangered}{(x^a)^b=x^{ab}}$When you have a power, and another power, you simply multiply
