So find 0.078 - (5.2 * 10 ^ -3 ) express your answer in scientific notation
To solve the equation 0.078 - (5.2 * 10 ^ -3), we first subtract the two numbers:
0.078 - 0.0052 = 0.0728
Now, we need to express the answer in scientific notation.
0.0728 can be written as 7.28 * 10 ^ -2.
Thus, the expression 0.078 - (5.2 * 10 ^ -3) in scientific notation is 7.28 * 10 ^ -2.
To find 0.078 - (5.2 * 10 ^ -3) and express the answer in scientific notation, follow these steps:
Step 1: Perform the subtraction
0.078 - (5.2 * 10 ^ -3) = 0.078 - 0.0052 = 0.0728
Step 2: Convert the result to scientific notation
0.0728 = 7.28 * 10 ^ -2
Therefore, the answer is 7.28 * 10 ^ -2 in scientific notation.
To solve the expression 0.078 - (5.2 * 10^(-3)) and express the answer in scientific notation, follow these steps:
Step 1: Perform the subtraction.
0.078 - (5.2 * 10^(-3)) = 0.078 - 0.0052 = 0.0728
Step 2: Express the answer in scientific notation.
To express 0.0728 in scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10. Count the number of times you move the decimal point, and that will determine the exponent.
In this case, we move the decimal point two places to the right to get 7.28. Hence, the exponent is -2 since we moved the decimal point two places to the right.
Therefore, the answer in scientific notation is 7.28 * 10^(-2).
