Question
1) 9³ - 6³ - 8³
>2) `sqrt(841) - sqrt(784) ` 3) `sqrt(5625) - sqrt(4984)` 4) 29² - 15 56 5) `root(3)(6859) - root(3)(5832)` (Q. 61-65) : Four of the five parts numbered (1), (2), (3), (4) and (5) are exactly equal. The number of that part which is not equal is your answer.Solution
Except 3, others are equal to 1 9³ - 6³ - 8³ = 729 – 216 – 512 = 1 `sqrt(841) - sqrt(784)` = 29-28 = 1 `sqrt(5625) - sqrt(4984)` = 75 -70 = 5 29² - 15 [if gte msEquation 12]>
