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

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
