Question

8
and 9, point, 9, times, 10, to the power 79.9×10
7
? Express your answer using either standard notation or scientific notation.

Answer 1

To find the difference between the two numbers, we can first simplify each expression:

9.6 x 10^89.6 x 10^8 = 9.6 x 10^89.6+8 = 9.6 x 10^97.6

9.9 x 10^79.9 x 10^7 = 9.9 x 10^79.9+7 = 9.9 x 10^86.9

Now, we can find the difference between the two numbers:

9.6 x 10^97.6 - 9.9 x 10^86.9 = (9.6 - 0.99) x 10^97.6 = 8.61 x 10^97.6

Therefore, the difference between the two numbers is 8.61 x 10^97.6.
