Answer:

hope this will help you...

Step-by-step explanation:

= (6^-2 + 3^-2) × (5/6)^-2

= (1/6^2 + 1/3^2) × (6/5)^2

= (1/6 + 1/3)^2 × (6/5)^2

By applying: (a+b)^2 = a^2 + 2ab + b^2

= (1/6)^2 + 2×1/6×1/3 + (1/3)^2 × (6/5)^2

= 1/36 + 1/9 + 1/9 × 36/25

= 1 + 4 + 4 × 36/25

36

= 9/36 × 36/25

= 9/25

= 0.36
