$3^y. 3^2. 3^{-4}$
$3^y. 3^2. 3^{-4}$
✓
Answer
$3^{y \cdot} \cdot 3^2 \cdot 3^{-4}$
$=3^y \cdot \frac{3^2}{3^4}=3^y=\frac{3 \times 3}{3 \times 3 \times 3 \times 3}$
$=3^y \times \frac{1}{3^2}=3^{y-2}$
$=3^y \cdot \frac{3^2}{3^4}=3^y=\frac{3 \times 3}{3 \times 3 \times 3 \times 3}$
$=3^y \times \frac{1}{3^2}=3^{y-2}$
