Answer 2

Answer:

Answer is 0.73

.

Explanation:

Formula: a^2 + b^2 -2ab = (a - b)^2

.

Put a=1.03 and b=0.3

.

Therefore,

1.03^2 + 0.3^2 - 2×1.03×0.3 = (1.03 - 0.3)^2

.

1.03×1.03 + 0.3×0.3 - 1.03×0.6 = (1.03-0.3)^2

.

1.03×1.03 + 0.3×0.3 - 1.03×0.6 = (1.03-0.3)x (1.03-0.3)

.

But 1.03-0.3= 0.73

Therefore,

1.03×1.03 + 0.3×0.3 - 1.03×0.6 = (1.03-0.3)x 0.73

.

Dividing on both sides by (1.03-0.3), we get,

(1.03×1.03 + 0.3×0.3 - 1.03×0.6) ÷ (1.03-0.3) = 0.73
