Question
(3.1-1.15)^2/0.005​
Solution 1

Answer for (3.1 - 1.15)²/0.005 is 760.5

Step-by-step explanation:

• Step 1: Given expression is (3.1 - 1.15)²/0.005
• Step 2: Simplify the expression using algebraic equation

(a - b)² = a² - 2ab + b². Here a = 3.1 and b= 1.15

⇒ (a - b)² = (3.1)² - 2×3.1×1.15 + (1.15)²

= 9.61 - 7.13 + 1.3225

= 10.9325 - 7.13 = 3.8025

• Step 3: Find the solution to the expression

⇒ (3.1 - 1.15)²/0.005 = 3.8025/0.005 = 760.5
