Question

Find the value of \(\frac{(0.03)^2-(0.01)^2}{0.03-0.01}\)
1. 0.4
2. 0.02
3. 0.04
4. 0.004

Answer 1

Correct Answer - Option 3 : 0.04

Concept Used:

a² - b² = (a + b)(a - b)

Calculation:

\(\frac{(0.03)^2-(0.01)^2}{0.03-0.01}\)

⇒ \({(0.03 + 0.01) \times (0.03 - 0.01)} \over (0.03 - 0.01)\)

⇒ (0.03 + 0.01)

⇒ 0.04

∴ The required value of the given expression is 0.04
