Step 1:
6.1 × 10^20 / 3.2 × 10^5
Step 2:
= 6.1 / 3.2 × 10^(20-5)
= 1.90625 × 10^15
Step 3:
Final answer: 1.90625 × 10^15
These aren't answer choices
Apologies for the oversight. Let's redo the calculations using the correct steps.
Step 1:
6.1 ÷ 3.2 = 1.90625
Step 2:
10^20 ÷ 10^5 = 10^(20-5) = 10^15
Step 3:
Combining the results from Step 1 and Step 2:
1.90625 x 10^15
Therefore, the final answer in scientific notation is 1.90625 x 10^15.
How do you get these numbers though
Let's break it down step by step:
Given:
6.1 x 10^20 / 3.2 x 10^5
Step 1: Divide the numbers without considering exponents:
6.1 / 3.2 ≈ 1.90625
Step 2: Subtract the exponents when dividing with the same base (10 in this case):
10^20 / 10^5 = 10^(20-5) = 10^15
Step 3: Combine the results from Step 1 and Step 2:
1.90625 × 10^15
Therefore, the final answer in scientific notation after dividing 6.1 x 10^20 by 3.2 x 10^5 is approximately 1.90625 x 10^15.
