Find 0.078 - (5.2 x 10^-3) express your answers in scientific notation
0.078 - (5.2 x 10^-3) = 0.078 - 0.0052 = 0.0728
Therefore, the answer is 7.28 x 10^-2 in scientific notation.
To subtract the numbers, we can rewrite them both in scientific notation.
0.078 can be written as 7.8 x 10^-2.
Similarly, 5.2 x 10^-3 remains the same.
Now, we can subtract:
7.8 x 10^-2 - 5.2 x 10^-3 = (7.8 - 5.2) x 10^-2 = 2.6 x 10^-2.
Therefore, the answer in scientific notation is 2.6 x 10^-2.
To get the answer to this question, we need to perform the subtraction operation and express the result in scientific notation. Let's break down the steps:
Step 1: Perform the subtraction.
Start by subtracting 5.2 x 10^-3 from 0.078:
0.078 - (5.2 x 10^-3)
To subtract these numbers, align the decimal points:
0.078
- 0.0052
Subtract the numbers:
0.0728
Step 2: Express the answer in scientific notation.
To express the answer in scientific notation, we need to move the decimal point to a position after the first nonzero digit and adjust the coefficient accordingly.
In this case, we can move the decimal point two places to the left to get a coefficient between 1 and 10. The original number 0.0728 becomes 7.28 x 10^-2.
Therefore, the answer expressed in scientific notation is 7.28 x 10^-2.
