Natalie tried to evaluate the expression \left( 4^{-3} \cdot 2^{-3} \right)^{0}(4 −3
⋅2
−3
)
0
left parenthesis, 4, start superscript, minus, 3, end superscript, dot, 2, start superscript, minus, 3, end superscript, right parenthesis, start superscript, 0, end superscript.
\begin{aligned} &\phantom{=}\left( 4^{-3} \cdot 2^{-3} \right)^{0} &=\left( 8^{-3}\right)^{0} &\text{Step } 1 &= 8^{0} &\text{Step } 2 &=0&\text{Step } 3 \end{aligned}
​

=(4
−3
⋅2
−3
)
0

=(8
−3
)
0

=8
0

=0

Step 1
Step 2
Step 3

Did Natalie make a mistake? If so, in which step?
