Calculate (4.8×10-3) -(9.4×10-6). Take time if necessary double check if your answer is correct. Be 100% right.
To subtract these numbers, we need to make sure they have the same exponent.
First, we can convert 4.8 × 10^-3 into scientific notation: 4.8 × 10^-3 = 4.8 × 10^-3 × 10^3 = 4800 × 10^-6.
So, the expression becomes:
(4800 × 10^-6) - (9.4 × 10^-6).
Now we can subtract the numbers before the exponent: 4800 - 9.4 = 4790.6.
Since the exponent is the same, the final answer is 4790.6 × 10^-6.
Therefore, (4.8 × 10^-3) - (9.4 × 10^-6) is equal to 4790.6 × 10^-6.
