Divide 6.1 x 1020 by 3.2 x 105. Express your answer in scientific notation.
I couldn't get the image.
6.1*10^20 / 3.2 * 10^5 = 6.1/3.2 * 10^20/10^5 = 1.91 * 10^15
To divide 6.1 x 10^20 by 3.2 x 10^5, we follow these steps:
Step 1: Divide the coefficients (6.1 ÷ 3.2 = 1.90625).
Step 2: Subtract the exponents (20 - 5 = 15).
Therefore, the answer in scientific notation is 1.90625 x 10^15.
To divide numbers expressed in scientific notation, divide the coefficient (the number part) and subtract the exponents.
Let's divide 6.1 x 10^20 by 3.2 x 10^5.
Step 1: Divide the coefficients: 6.1 ÷ 3.2 = 1.90625.
Step 2: Subtract the exponents: 20 - 5 = 15.
Therefore, the answer is 1.90625 x 10^15 in scientific notation.
