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?
