Find 0.078−(5.2×10−3). Express your answer in scientific notation. Do not round your answer.(1 point)
0.078 - (5.2 × 10^-3) can be expressed in scientific notation as 7.8 × 10^-2.
To subtract 5.2×10^(-3) from 0.078, we can rewrite both numbers in scientific notation so that we can easily subtract them.
0.078 can be written as 7.8×10^(-2) (move the decimal point two places to the left)
5.2×10^(-3) is already in scientific notation.
Now we can subtract the two numbers:
7.8×10^(-2) - 5.2×10^(-3) = (7.8 - 5.2) × 10^(-2) = 2.6×10^(-2)
Therefore, the answer is 2.6×10^(-2) in scientific notation.
To evaluate 0.078 - (5.2 × 10^-3), we need to subtract the second number from the first number.
0.078 - (5.2 × 10^-3) can also be written as 0.078 - 0.0052.
Subtracting these two numbers gives: 0.0728.
To express the answer in scientific notation, we can write it as 7.28 × 10^-2.
