Simplify the expression using one of the power rules. $$(5 z)^{3}$$
Added by Scott T.
Step 1
In this case, we have: $$(5z)^3 = (5z)^{1+2}$$ We can rewrite this as: $$(5z)^3 = 5^1z^2\cdot 5^1z^1$$ Now we can simplify by multiplying the coefficients and adding the exponents of $z$: $$(5z)^3 = 5^2z^3 = 25z^3$$ Show more…
