Answer 2

Answer:

(i) 2$\frac{3}{5}$ (ii) $x^{2} + y^{2}$

Step-by-step explanation:

Please mark brainliest and follow

(i) 2$\frac{3}{5}$ =$\frac{13}{5}$                   1 $\frac{3}{7}$=$\frac{10}{7}$

     LCM of denominators (5,7)=35

$\frac{13}{5} * \frac{7}{7} =\frac{91}{35}$               $\frac{10}{7} * \frac{5}{5} = \frac{50}{35}$

                91   ≥  35

Therefore 2$\frac{3}{5}$ is greater than 1 $\frac{3}{7}$

(ii) Sqaure of x= x²

    Square of y= y²

    Sum of squares is x²+y²

Additional steps:

x²+y²=(x+y)²-2xy               [(a+b)²=a²+b²+2ab]

Note: The spelling of (algebric exprasion) is algebraic expression. Please correct to get better marks. :)
