3.2 x 10^4 + 32.8

Question

step by step

Answer 1

To add two numbers in scientific notation, the first step is to make sure the exponents are the same. In this case, the exponent of 3.2 x 10^4 is 4, and the exponent of 32.8 is 0.

To align the exponents, we can write 32.8 as 3.28 x 10^1.

Now that the exponents are the same, we can add the numbers:

3.2 x 10^4 + 3.28 x 10^1

= (3.2 + 3.28) x 10^4

= 6.48 x 10^4

So, 3.2 x 10^4 + 32.8 = 6.48 x 10^4.
