a = 1.01, b = 0.01, x = 7.85, y = 2.15
Formula used:
Calculations:
For 1st term :
⇒ a + b = 1.01 + 0.01 = 1.02
⇒ a − b = 1.01 − 0.01 = 1
⇒ a² = 1.0201, ab = 1.01 × 0.01 = 0.0101, b² = 0.0001
⇒ a² − ab + b² = 1.0201 − 0.0101 + 0.0001 = 1.0101
⇒
For 2nd term:
⇒ x + y = 7.85 + 2.15 = 10
⇒ x − y = 5.7
⇒
⇒ Result=1.0101 × 10 = 10.101
∴ The value of the expression is 10.101.
