Question

The area of a desert land is approximately ${10}^3$ sq km. Which of the following gives the area in the standard form?

• A. 100,000 sq km
• B. 10,000 sq km
• C. 100 sq km
• D. 1,000 sq km

Answer 1

The correct option is D 1,000 sq km

The area of the desert land is given as ${10}^3$ sq km.

Here, the base of ${10}^3$ is 10 and the exponent is 3.

To find the value of ${10}^3$, we have to multiply 10 by itself, three times.

${10}^3$ = 10 $\times$ 10 $\times$ 10

= 1000

$⟹$ ${10}^3$ = 1000

Hence, the area of the desert land is 1,000 sq km.
