Question

round the following measurement to the indicted number of significant figures. to enter scientific notation use the \e\ form. for example 1.25 x 10^3 = 1.25e3
1.468352 x 10^3 mg to 5 significant figures
1.458400e x mg

Explanation:

Step1: Identify significant figures

The given number is $1.468352\times 10^{3}$. We want 5 significant figures.

Step2: Round the number

The first 5 digits are 1, 4, 6, 8, 3. The next digit is 5. According to rounding rules, when the digit to be dropped is 5, we round up if the preceding digit is odd. So $1.468352\times 10^{3}$ rounded to 5 significant figures is $1.4684\times 10^{3}$. In the "e" form, it is $1.4684e3$.

Answer:

$1.4684e3$ mg
