(C) First,convert the mixed fraction into an improper fraction:$21 \frac{15}{289} = \frac{21 	imes 289 + 15}{289} = \frac{6069 + 15}{289} = \frac{6084}{289}$Now,find the square root:$\sqrt{\frac{6084}{289}} = \frac{\sqrt{6084}}{\sqrt{289}} = \frac{78}{17}$Convert the improper fraction into a mixed fraction:$\frac{78}{17} = 4 \frac{10}{17}$To make the result a whole number,we must subtract the fractional part:$4 \frac{10}{17} - \frac{10}{17} = 4$Therefore,the least number to be subtracted is $\frac{10}{17}$.

What least number should be subtracted from the square root of $21 \frac{15}{289}$ so that the result is a whole number?
