Question

How can $10\times 10\times 10\times 10$ be expressed in an exponent form?

• A. $10\times 4$
• B. $10\times 5$
• C. ${10}^4$
• D. ${10}^5$

Answer 1

The correct option is C ${10}^4$

$10\times 10\times 10\times 10$ is $10$ multiplied $4$ times, which we can write in an exponent form as ${10}^4$.

In ${10}^4$, the base is $10$ and the exponent is $4$, which denotes the number of times the base needs to be multiplied.

$\underset{–}{\text{Note:}}{10}^4$ can be pronounced as
$\bullet 10$ to the $4^{\text{th}}$ power;
$\bullet 10$ to the $4^{\text{th}}$;
$\bullet 10$ raised to the $4^{\text{th}}$ power

$\therefore$ Option (c.) is the correct one.
