Question

1. what is the value of the expression below?

$3^5 = $
(there are some hand - written calculation processes: $3×3×3×3×3$, $9×9×3$, $81×3$ and a blank rectangle)

Explanation:

Step1: Expand the exponential expression

$3^5 = 3 \times 3 \times 3 \times 3 \times 3$

Step2: Multiply first two factors

$3 \times 3 = 9$, so $9 \times 3 \times 3 \times 3$

Step3: Multiply next two factors

$9 \times 3 = 27$, so $27 \times 3 \times 3$

Step4: Multiply next two factors

$27 \times 3 = 81$, so $81 \times 3$

Step5: Calculate final product

$81 \times 3 = 243$

Answer:

243
