Answer:

$\frac{3}{4}(m+n)-\frac{1}{4}(m-n) = \frac{14}{24}$

Step-by-step explanation:

Given

$\frac{3}{4}(m+n)-\frac{1}{4}(m-n);m=\frac{1}{2},n=\frac{1}{3}$

Required

Solve

To do this, we simply substitute values of m and n in the given expression

$\frac{3}{4}(\frac{1}{2}+\frac{1}{3})-\frac{1}{4}(\frac{1}{2}-\frac{1}{3})$

Evaluate the brackets

$\frac{3}{4}(\frac{3 + 2}{6})-\frac{1}{4}(\frac{3-2}{6})$

$\frac{3}{4}(\frac{5}{6})-\frac{1}{4}(\frac{1}{6})$

Open Brackets

$\frac{15}{24} - \frac{1}{24}$

Take LCM

$\frac{15 - 1}{24}$

$\frac{14}{24}$

Hence:

$\frac{3}{4}(m+n)-\frac{1}{4}(m-n) = \frac{14}{24}$

Please help me!!! I don't understand how to solve it(((

$\sqrt{( \sqrt{7-2 \sqrt{10} }+ \sqrt{2} )*2 \sqrt{5} }= \\ = \sqrt{( \sqrt{2-2 \sqrt{2*5}+5 }+ \sqrt{2} )*2 \sqrt{5} }= \\ \sqrt{( \sqrt{( \sqrt{2}- \sqrt{5})^{2} }+ \sqrt{2} )*2 \sqrt{5} }= \\ \sqrt{( \sqrt{5}- \sqrt{2} + \sqrt{2} )*2 \sqrt{5} }= \\ \sqrt{ \sqrt{5} *2 \sqrt{5} }= \\ \sqrt{2*5} = \sqrt{10}$
HAVE A NICE DAY!! ^^
