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

1 answer

To subtract these numbers in scientific notation, we need to make sure that the exponents are the same.

We can rewrite 4.8×10^(-3) as 0.0048×10^0 and 9.4×10^(-6) as 0.0094×10^0.

Now, subtracting these two numbers we get:

0.0048×10^0 - 0.0094×10^0

= (0.0048 - 0.0094) × 10^0

= -0.0046 × 10^0

Finally, converting it back to scientific notation, we get:

= -4.6×10^(-3)

Rounding to 2 decimal places, we get the final answer as -4.60×10^(-3).
