To add 3.2 x 10^4 and 1.95 x 10^6, we need to make sure the numbers have the same exponent.
Step a:
3.2 x 10^4 = 0.32 x 10^5 (rewrite as 0.32 multiplied by 10 raised to the power of 5)
Step b:
1.95 x 10^6 = 19.5 x 10^5 (rewrite as 19.5 multiplied by 10 raised to the power of 5)
Now that both numbers have the same exponent (10^5), we can add them:
0.32 x 10^5 + 19.5 x 10^5 = (0.32 + 19.5) x 10^5 = 19.82 x 10^5
Therefore, the sum of 3.2 x 10^4 and 1.95 x 10^6 is 19.82 x 10^5.
