Question

1/3.40*(10)^24 write this in round off to two digits

Answer 1

Round off to 2 digits for given value

• To find the round off values, the exponential form must be converted into decimal form.
• To convert it into the decimal form, the following calculation is done:

$\frac{1}{3.40\times10^{24}} = \frac{1}{3.40}\times10^{-24} = 0.294117\times10^{-24}$

• As per the rules for identification of significant number, the zero preceding the numbers as well as the decimals are not considered as significant.
• Thus the first two significant numbers in the given case are 29. The number followed by 9 is four which is less than 5.
• Due to this reason, 4 doesn't influences 9. Thus the round off value of the given number to 2 significant figures is 29.
• Thus the round off to 2 digits value for $\frac{1}{3.40\times10^{24}}$ = $29\times10^{-26}$.
