Question

Which number is one million times larger than 8.7 x 104 ? A) 8.7 x 107 B) 8.7 x 108 C) 8.7 x 109 D) 8.7 x 1010

Answer 1

Assuming the numbers after 10 are exponents:

1 million is equal to 10^6. Let's multiply this by the original expression.
8.7*10^4*10^6

Add exponents when multiplying with the same base
10^4*10^6= 10^10

Final answer: 8.7*10^10, or D

Answer 2

D)
`8.7 * 10^(10)`

Explanation:

The question is correctly written as below:

Which number is one million times larger than
`8.7 * 10^(4)`?

A)
`8.7 * 10^(7)`

B)
`8.7 * 10^(8)`

C)
`8.7 * 10^(9)`

D)
`8.7 * 10^(10)`

Consider
`8.7 x 10^(4)` to be number A and number B is one million times (
`10^(6)`) greater than number A

`B = A * 10^(6)`

`B = 8.7 * 10^(4) * 10^(6)`

`B = 8.7 * 10^(4+6)`

`B = 8.7 * 10^(10)`

D)
`8.7 * 10^(10)`
