simplify the expression 0.078×0.0071/0.13×0.071 using scientific notation and express your answer in scientific notation.

Answer 1

To simplify the expression, we will first perform the calculations and then convert the result to scientific notation.

0.078 × 0.0071 / 0.13 × 0.071

= 0.0005538 / 0.00923

= 0.05999

Since 0.05999 is already in decimal form, we can convert it to scientific notation by moving the decimal point three places to the right:

= 5.999 × 10^(-2)

Therefore, the simplified expression in scientific notation is 5.999 × 10^(-2).
