Some equations are solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis. If `324 xx 289 = 35, 441 xx 484 = 43, 625 xx 400 = 45`, find the value of `256 xx 729`.

A

33

B

35

C

43

D

34

Text Solution

Verified by Experts

The correct Answer is:
C
`sqrt(324) = 18 : sqrt(289)=17`
`18 + 17 = 35`
` sqrt(441) = 21 , sqrt(484) = 22 `
` sqrt(625 ) = 25 , sqrt(400)=20`
` 25 + 20 = 45`
` sqrt(256 ) = 16 , sqrt(729)=27`
` 16 + 27 = 43 `
