Question

For visualising the power $2^7$ using dots, we need dots in all.

• A. $256$
• B. $64$
• C. $512$
• D. $128$

Answer 1

The correct option is D $128$

$2^7=2\times 2\times 2\times 2\times 2\times 2\times 2$
$=128$
Thus, for visualising the power $2^7$ using dots, we need a total of $128$ dots.
