Answer 2

Answer:

5/2

Step-by-step explanation:

=$\frac{3 + 2}{4 + 2}$

=$\frac{3 + 2}{4 + 2} \times \frac{4 - 2}{4 - 2}$

in the above step rationalise the denominator

=$\frac{3 + 2 \times 4 - 2}{16 - 4}$

denominator changed by the identity

$(a + b)(a - b) = {a}^{2} - {b}^{2}$

=$\frac{5 \times 2}{12}$

$= \frac{10}{12}$

$= \frac{5}{6}$

this is your answer after rationalising

have a nice day☺☺
