Let the unknown number be n.
(n x 32) - 7 = 68
n x 32 = 68 + 7 = 75
9n = 75
n = 75/9 = 8⅓ Another answer: the above answer is correct in one interpretation on the text based question. Alternatively you could read it as (3n)^2 - 7 = 68 (3n)^2 = 75 9 n^2 = 75 n^2 = 8.33 n = 2.89 however I suspect you were trying to describe: 3 (n^2) - 7 = 68 3 (n^2) = 75 n^2 = 25 n = 5

2 times 739 minus !6 equals 117,743,173,416,535,106
-2 times -2 = plus 4 since minus times minus is plus
Four times 3^2 minus two = 34.

The answer is 1, whatever the value of a.
It is 500b-1.
-68 I think
it equals 18 times 18. 18 times 18 equals 324. 324 is your answer.
