Whats 3.2x10^4 + 1.95x10^6? write it in scientific notation, show your work.

Answer 1

To add the given numbers in scientific notation, we need to make sure both numbers have the same power of 10.

3.2x10^4 can be written as 0.32x10^5 since we multiplied the coefficient by 10, and divided the power of 10 by 10.

Now, we can add these numbers:
0.32x10^5 + 1.95x10^6

To add numbers with the same power of 10, we sum their coefficients:
0.32 + 1.95 = 2.27

Since both numbers had the same power of 10, we can keep it unchanged:
2.27x10^6

Therefore, the sum of 3.2x10^4 and 1.95x10^6 in scientific notation is 2.27x10^6.
