If 3^x*4^y = 531,441 and x – y = 12, then x = ?
If 3^x*4^y = 531,441 and x – y = 12, then x = ?
Answer/Solution
12
Steps/Work
Since 531,441 is an odd number, it is not a multiple of 4.
This means that y must equal zero.
Since x - y = 12 and y = 0, then x = 12.
The answer is C.
This means that y must equal zero.
