यदि `16 - 2 = 2, 9 -3 = 0, 81 - 1 = 8`,तो `64 - 4 = `क्या है ?

Options

A. 4
B. 2
C. 6
D. 8

Answer

A

Explanation

`16 - 2 = 2`
` rArr 16 = (2 + 2)^(2) = (4)^(2)`
` 9 -3 = 0`
`rArr 9 = (3 +0)^(2) = (3)^(2)`
` 81 - 1 = 8`
`rArr 81 = (1 + 8)^(2) = (9)^(2)`
उसी प्रकार ,
`64 - 4 = ?`
` rArr 64 = (4 +4)^(2) = (8)^(2)`
