Question

Divide. Write your answer in scientific notation.
(9 x 10^1)/ (9 x 10^7)

Answer 1

To divide (9 x 10^1) by (9 x 10^7) and express it in scientific notation, we divide the coefficients and subtract the exponents resulting in 1 x 10^-6.

Step-by-step explanation:

To divide the given numbers and write the answer in scientific notation, we follow these steps:

1. Divide the coefficients (numbers out front) and keep the exponents separate: (9 / 9).
2. Subtract the exponents: 101 - 107.
3. Since 9 divided by 9 equals 1, and using the laws of exponents, 101 - 107 equals 10-6, we obtain the final result in scientific notation as 1 x 10^-6.

So, the division (9 x 101) / (9 x 107) results in 1 x 10^-6.
