Question

Q7 all parts pls help guys in maths

Answer 1

Hey dear, here's ur answer

(a)

$\frac{ \sqrt{5} }{2 \sqrt{3} }$

$\frac{2.236}{2(1.732)}$

$\frac{2.236}{3.464}$

$= 0.645496535$

(b)

$\frac{1}{2 + \sqrt{3} }$

$\frac{1}{2 + 1.732}$

$\frac{1}{3.732}$

$= 0.26795284$

(c)

$\frac{3 - 2 \sqrt{2} }{3 + 2 \sqrt{2} }$

$\frac{1(1.414)}{5(1.414)}$

$\frac{1.414}{7.071}$

$= 0.19991715$

(d)

$\frac{4}{ \sqrt{7} + \sqrt{3} }$

$\frac{4}{ 2.645 + 1.730}$

$\frac{4}{4.375}$

$= 0.914285714$

HOPE IT HELPS UH!
