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

Answer:

D) $8.7 * 10^{10}$

Step-by-step 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) $8.7 * 10^{10}$
