Answer 1

Simplify:

Step-by-step explanation:

$\ Given \ value: \\\\16-9 (a+b)\ power\ of \ 2 \ factories\\\\\ Solution: \\\\16-9 (a+b)^2\\\\\ Formula: (a+b)^2 =a^2+b^2+2.a.b \\\\\rightarrow 16 - 9(a^2+b^2+2ab)\\\\\rightarrow 16- 9a^2-9b^2-18ab=0\\\\\rightarrow 9(a^2+b^2)+18ab-16=0\\\\\rightarrow 9((a^2+b^2)+2ab)=16\\\\\rightarrow ((a^2+b^2)+2ab)=\frac{16}{9}$

$\rightarrow (a+b)^2=(\frac{4}{3})^2 \\\\\rightarrow (a+b)=\frac{4}{3}$
