Question

The cost to build a house is 10,000 dollars. Find which of the following gives the total cost to construct 100 houses in exponent form.

• A. ${10}^2$
• B. ${10}^6$
• C. 10 $\times$ 10 $\times$ 10 $\times$ 10
• D. 10 $\times$ 10 $\times$ 10 $\times$ 10 $\times$ 10

Answer 1

The correct option is B ${10}^6$

Cost to build a house = 10,000 dollars

Cost to build 100 houses = 100 $\times$ 10,000

= 1,000,000 dollars

= ${10}^6$ dollars

Hence, the cost in exponential form is ${10}^6$ dollars
