Answer» Correct Answer - Option 3 : 10 Given: 3 * 4 = 5 2 * 5 = √29 Calculations: (32 + 42)1/2 = (9 + 16)1/2 ⇒ (25)1/2 = 5 (22 + 52)1/2 = (4 + 25)1/2 ⇒ (29)1/2 = √29 In the same way (62 + 82)1/2 = (36 + 64)1/2 ⇒ (100)1/2 = 10 ∴ The required value is 10 It is in the form of Pythagoras theorem a2 + b2 = c2 \(\sqrt{a^2 + b^2} = c \) |
