Question

find the value by identity 1
(3/5a+2/3b) power of 2​

Answer 1

Step-by-step explanation:

$we \: know \: that \: (a + b) ^{2} = {a}^{2} + 2ab + {b}^{2}$

$(\frac{3}{5} a + \frac{2}{3} b) ^{2}$

$= ( \frac{3}{5} a) ^{2} + 2 \times \frac{3}{5} a \times \frac{2}{3} b + ( \frac{2}{3} b) ^{2}$

$= \frac{9}{5} {a}^{2} + \frac{4}{5}a b + \frac{4}{9} {b}^{2}$
