what is 3.2*10^4 + 1.95*10^6

7 answers

To add these numbers, we need to make sure the exponents are the same. In this case, both numbers are in scientific notation with exponents of 4 and 6. We can rewrite the numbers as:

3.2 * 10^4 = 32,000
1.95 * 10^6 = 1,950,000

Now we can add the numbers:

32,000 + 1,950,000 = 1,982,000

Therefore, 3.2 * 10^4 + 1.95 * 10^6 equals 1,982,000.
what is 8.03 * 10^-8 - 2.56 * 10 ^-2
To subtract these numbers, we need to make sure the exponents are the same. In this case, both numbers are in scientific notation with exponents of -8 and -2. We can rewrite the numbers as:

8.03 * 10^-8 = 0.0000000803
2.56 * 10^-2 = 0.0256

Now we can subtract the numbers:

0.0000000803 - 0.0256 = -0.0255999197

Therefore, 8.03 * 10^-8 - 2.56 * 10^-2 equals -0.0255999197.
what is 3.2 * 10^4 * 2.56 * 10^-2
To multiply numbers in scientific notation, you can multiply the coefficients and add the exponents.

Given:
3.2 * 10^4 * 2.56 * 10^-2

First, multiply the coefficients:
3.2 * 2.56 = 8.192

Next, add the exponents:
10^4 * 10^-2 = 10^(4 - 2) = 10^2 = 100

Finally, combine the coefficient and exponent:
8.192 * 100 = 819.2

Therefore, 3.2 * 10^4 * 2.56 * 10^-2 equals 819.2.
what is 1.95 * 10^6 / 4.82 * 10^12
To divide numbers in scientific notation, you need to divide the coefficients and subtract the exponents.

Given:
1.95 * 10^6 / 4.82 * 10^12

First, divide the coefficients:
1.95 / 4.82 ≈ 0.40414

Next, subtract the exponents:
10^6 / 10^12 = 10^(6 - 12) = 10^(-6)

Finally, combine the coefficient and exponent:
0.40414 * 10^(-6) ≈ 4.0414 * 10^(-7)

Therefore, 1.95 * 10^6 / 4.82 * 10^12 is approximately 4.0414 * 10^(-7).
