Answer:
(245 / (6^2 - 1)) + 15 = 22
Step-by-step explanation:
Well we need to divide 245 by something - and by something that divides it, otherwise we can't solve this. It's not divisible by 6^2 = 36, it's not divisible by 6^2 - 1 + 15 = 50 and it's not divisible by 6^2 - (1 + 15) = 20. Our only option is (6^2 - 1) = 35
245/35 = 7 and we notice that 7 + 15 = 22, so we've solved it.
