Fill in the blanck:
$(0.05)^3$ = ________.
$(0.05)^3$ = ________.
✓
Answer
$(0.05)^3=\underline{\mathbf{0 . 0 0 0 1 2 5}}$
First, we will find the product $0.05 \times 0.05 \times 0.05$
Now, $5 \times 5 \times 5=125$
Sum of decimal places in the given decimals $=(2+2+2)=6$
So, the product must have six decimal places
$\therefore(0.05)^3=0.05 \times 0.05 \times 0.05=0.000125$
