To subtract these numbers, we need to make sure the exponents are the same. Let's rewrite them using scientific notation:
3.2 x 10^4 - 4.82 x 10^12 = 3.2 x 10^4 - 4.82 x 10^4 x 10^8
Since both numbers are multiplied by 10^4, we can subtract the decimal parts:
3.2 - 4.82 x 10^8
The exponents are now the same, so we can subtract the coefficients:
3.2 - 4.82 = -1.62
Therefore, 3.2 x 10^4 - 4.82 x 10^12 is equal to -1.62.
3.2x10^4-4.82x10^12
