3.2 x 10^4 - 1.95 x 10^6
Please show work with scientific notation
To subtract numbers in scientific notation, we need to make sure the exponents are the same.
Given:
3.2 x 10^4
- 1.95 x 10^6
To make the exponents the same, we need to shift the decimal point in the second number to the left by 2 places:
1.95 x 10^6 = 0.0195 x 10^8
Now we can subtract the numbers:
3.2 x 10^4 - 0.0195 x 10^8
Since the exponents are the same, we just have to subtract the coefficients:
3.2 - 0.0195 = 3.1805
The final answer is 3.1805 x 10^4.
