Subtract 1.95 x 10^6 and 3.2 x 10^4

Answer 1

To subtract the two numbers in scientific notation, we need to ensure that their exponents are the same.

Given:
1.95 x 10^6
3.2 x 10^4

First, let's rewrite the second number in scientific notation with an exponent of 6:
3.2 x 10^4 = 3.2 x 10^(6-2) = 3.2 x 10^2

Now, we can subtract the numbers:
1.95 x 10^6 - 3.2 x 10^2 = (1.95 - 3.2) x 10^6 = -1.25 x 10^6

Therefore, the subtraction of 1.95 x 10^6 and 3.2 x 10^4 is -1.25 x 10^6.
