Question

The value of $5\times {10}^5$ is
.

• A. $500,000$
• B. $5,000,000$
• C. $50,000$

Answer 1

The correct option is A $500,000$

$5\times {10}^5$
$=5\times \left({10}^5\right)$
$=5\times (100,000)$
($\because$ exponent of ${10}^5=5=$ number of zeros after $1$)

$=500,000$

$\underset{–}{\text{Note:}}5\times {10}^5\ne (5\times 10{)}^5$
