'7$8@8^7^0

7/8$87

Answer 2

we have

4(4*1/2 + 4*1/2) - 3{(1/√2)²-(1)²}

=4(2+2)-3(1/2 -1)

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

$= 16 - 3 (\frac{ - 1}{2} )$

$= 16 -( - \frac{3}{2} )$

$= 16 + (\frac{3}{2} )$

$take \: lcm \: of \: the \: above \: equatin$

$= \frac{32 + 3}{2} = \frac{35}{2} = 17.5$

hope you get it right........

if right mark as brainliest....
