If I divided 1.23x10^-10 and 1.4x10^-8, would my answer be 0.88x10^-18?
If I divided 1.23x10^-10 and 1.4x10^-8
(1.23*10^-10)/(1.4*10^-8)
= 8. 7857 * 10^-14
8.7857 x 10^-3
To divide numbers in scientific notation, we must divide their coefficients and subtract the exponents of 10.
In this case, we have:
1.23 × 10^-10 ÷ 1.4 × 10^-8
First, let's divide the coefficients: 1.23 ÷ 1.4 = 0.8785714285714286 (rounded to 16 decimal places).
Next, let's subtract the exponents: -10 - (-8) = -10 + 8 = -2.
So, the result is 0.8785714285714286 × 10^-2.
Now, we can simplify the result by moving the decimal point two places to the left, which will increase the exponent by 2: 0.8785714285714286 × 10^-2 = 8.785714285714286 × 10^-4.
Therefore, the correct answer is 8.785714285714286 × 10^-4, not 0.88 × 10^-18 as you mentioned.
