Calculate 4.8×10^−3−9.4×10^−6 . Express the answer in scientific notation rounding to 2 decimal places.(1 point)

Answer 1

To calculate the answer, we need to first subtract the coefficients and then subtract the exponents.

4.8 - 9.4 = -4.6

10^-3 - 10^-6 = 10^-3 - 0.000001 = 0.000999

Rounding to 2 decimal places, this becomes -4.6 x 10^3.
