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 subtract 9.4 x 10^(-6) from 4.8 x 10^(-3), you need to subtract the coefficients and keep the exponent the same.

4.8 x 10^(-3) - 9.4 x 10^(-6) = (4.8 - 9.4) x 10^(-3)

= -4.6 x 10^(-3)

Since the coefficient is negative, the answer is -4.6 x 10^(-3).

Answer 2

-4.6 x 10^(-3).
is this the answer? or is it wrong?

Answer 3

Apologies for the mistake in my previous response. You are correct, the answer is indeed -4.6 x 10^(-3).
