Let's X=ab = 10a + b for example: 23 = 2x10 + 3 From the thesis 1) (a + b)x8 -2 = 10a + b 2) (a-b)x15 + 2 = 10a + b Using both of them, we got: -2a + 7b -2 = 0 and 5a - 16b + 2 = 0 Solve the two equations, we have a=6, b=2 Regards!

Agree with you: the same formula is 3C6.

Thanks all you!

What is the problem with this sentence? “While it is true all deserts are dry, all deserts are hot is a popular myth.”

Yup. OA is A. Thanks a lot!
