use 3.2x10^4 and 1.95 x 10^6 for steps a,b,c,d. Answers MUST be in correct scientific notation. show work
b. Subtract 1.95 x 10^6 and 3.2 x 10^4
1.95 x 10^6 - 3.2 x 10^4
To subtract these numbers, we need to subtract the coefficients and keep the same exponential term.
1.95 - 0.032 = 1.918
Since both numbers have the same exponential term (10^6), we keep it in the answer.
Therefore, the answer is 1.918 x 10^6
To subtract 1.95 x 10^6 and 3.2 x 10^4, you need to ensure that the exponents of the powers of 10 are the same. In this case, both numbers are already in scientific notation, so you can directly subtract the decimal parts.
1.95 x 10^6 - 3.2 x 10^4 = 1.95 x 10^6 - 0.032 x 10^6
Now, you can subtract the decimal parts: 1.95 - 0.032 = 1.918
Finally, write the result in scientific notation. Since you are subtracting 10^4 from 10^6, the exponent remains the same.
1.95 x 10^6 - 3.2 x 10^4 = 1.918 x 10^6
To subtract 1.95 x 10^6 and 3.2 x 10^4, we need to subtract the coefficients and keep the common exponential term.
1. Convert both numbers to scientific notation if not already in that form:
1.95 x 10^6 and 3.2 x 10^4
2. Subtract the coefficients:
1.95 - 3.2 = -1.25
3. Keep the common exponential term:
10^6 (since the larger number has an exponent of 6)
4. Rewrite the answer in scientific notation:
-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.
