To add these numbers in scientific notation, we need to make sure that the exponents are the same.
First, let's write both numbers with the same exponent. We can do this by moving the decimal point in 3.2 × 10^4 two places to the right:
3.2 × 10^4 = 0.32 × 10^6
Now we can add the numbers:
0.32 × 10^6 + 1.95 × 10^6 = (0.32 + 1.95) × 10^6 = 2.27 × 10^6
So, the sum of 3.2 × 10^4 and 1.95 × 10^6 in scientific notation is 2.27 × 10^6.

To subtract these numbers in scientific notation, we need to make sure that the exponents are the same.
First, let's write both numbers with the same exponent. We can do this by moving the decimal point in 1.95 × 10^6 four places to the left:
1.95 × 10^6 = 0.000195 × 10^6
Now we can subtract the numbers:
3.2 × 10^4 - 0.000195 × 10^6 = (3.2 - 0.000195) × 10^4 = 3.199805 × 10^4
So, the difference between 3.2 × 10^4 and 1.95 × 10^6 in scientific notation is 3.199805 × 10^4.

Sure! To write the number -1.918 × 10^4 in scientific notation, we need to move the decimal point so that there is only one non-zero digit to the left of it.
In this case, the decimal point is already after the first non-zero digit (1), so we don't need to move the decimal point. However, since we have a negative sign in front of the number, we keep it with the number.
Therefore, -1.918 × 10^4 is the correct representation in scientific notation.
