When simplified\((256)^{(4)^{\frac{3}{2}}}\) is

Solution
\(=left ( 256 right )frac{1}{2^{3}}=256^{frac{1}{8}}=frac{1}{left ( 256 right )^{frac{1}{8}}}=frac{1}{left ( 2^{8} right )^{frac{1}{8}}}=frac{1}{2}\)
The value of \(\frac{1}{15}+\frac{1}{35}+\frac{1}{63}+\frac{1}{99}+\frac{1}{143}\) is

Solution
\(frac{1}{15}+frac{1}{35}+frac{1}{63}+frac{1}{99}+frac{1}{43}\)
\(frac{1}{3times 5}+frac{1}{5times 7}+frac{1}{7times 9}+frac{1}{9times 11}+frac{1}{11times 13}\)
\(=frac{1}{2}left ( frac{1}{3}frac{1}{5}+frac{1}{5}frac{1}{7}+frac{1}{7}frac{1}{11}+frac{1}{11}frac{1}{13} right )\)
\(=frac{1}{2}left ( frac{1}{3}frac{1}{13} right )=frac{1}{2}left ( frac{133}{39} right )=frac{5}{39}\)
If \(\sqrt{4096}=64\), then the value of,\(\sqrt{4096}+\sqrt{0.4096}+\sqrt{0.004096}+\sqrt{0.00004096}\) is

Solution
Given,\(sqrt{4096}=64\)
∴\(sqrt{4096}+sqrt{0.4096}+sqrt{0.004096}+sqrt{0.00004096}\)
= 6.4 + 0.64 + 0.064 + 0.0064 = 7.1104
A horse is tied with a rope of length 7 m at one corner of a square field having side equal to 10m. The minimum possible area of the square field that is left ungrazed is (given π = 22/7)

Solution
Let ABCD be a square field and the length of
the side be equal to 10m.
∵Reqd. minimum possible area of ungrazed
field left = ABPQDA\(=left ( 10 right )^{2}frac{1}{4}times pi (7)2\)
= 100 ^{1}⁄_{4} ×^{2}⁄_{7} ×7 ×7
\(=100frac{77}{2}=frac{123}{2}=61.5m^{2}\)
A mixture of milk and water is such that the quantity of milk is ^{3}⁄_{5} that ofwater. The proportion of milk in the mixture is

Solution
According to the question,
∴ Quantity of milk = ^{3}⁄_{5} × Quantity of water
\(Rightarrow frac{Quantity ; of ; milk ; in ; mixture}{Quantity ; of ; water ; in ; mixture } = frac{3}{5} = 3 : 5\)
∴ Reqd. proportion of milk in the mixture
\(frac{3}{(5+3)}=frac{3}{8}\)
