Question

(2 root5 + 3 root2 ) whole square

Answer 1

(2$\sqrt{5}$+3$\sqrt{2}$)² 

We know that          (a+b)² = a² + b² +2ab

(2$\sqrt{5}$)² +  (3$\sqrt{2}$)²  + 2×2$\sqrt{5}$×3$\sqrt{2}$

20 + 18  + 12$\sqrt{10}$

38+12$\sqrt{10}$

Answer 2

Answer:

38+12√10

Step-by-step explanation:

(2√5+3√2)^2

(a+b) ^2=a^2+2ab+b^2

(2√5)^2+2×2√5×3√2+(3√2)^2

4×5+12√10+9×2

20+12√10+18

38+12√10
