Answer 1

Step-by-step explanation:

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

=(0.9+0.36)(0.9-0.36)

Calculate this you will find answer

Answer 2

Answer:

hope it will help

Step-by-step explanation:

a-b = 0.9

Squaring on both sides

(a-b)² = 0.9²

a²-2ab+b² = 0.81

a²-2×0.36+b²=0.81

a²-0.72+b² = 0.81

a²+b² = 0.81+0.72

a²+b²=1.53
