0.00117 + 0.585 = ?

Solution
\(\frac{0.00117}{0.585}\)
\(=\frac{117}{100000}\times \frac{1000}{585}\)
\(=\frac{1}{100\times 5 }=\frac{0.2}{100}= 0.002\)
The average of the squares of the first six natural numbers is

Solution
We know that
\(1^{2} + 2^{2} + 3^{2} +.......+ n^{2}\)\(=\frac{n(n + 1)(20 + 1)}{6}\)
∴1^{2} + 2^{2} + 3^{2} +...... +6^{2}
\(=\frac{6(6+1\times 2\times 6+1)}{6}= 91\)
∴Average=\(\frac{91}{6}=15\frac{1}{6}\)

Solution
Let 0.89 = a and 0.64 = b.
∴ Expression =\(=\frac{a^{3}b^{3}}{a^{2} +ab+b^{2}}\)
\(=\frac{(a  b)(a^{2} + ab + b^{2})}{a^{2} +ab+b^{2}}\)
= a  b = 0.89  0.64 = 0.25
