You just solve for y.
y=<span><span><span>13/11</span>x</span>+<span>12/<span>11</span></span></span>
So, the questions is 6^(-6) * 6^(-1).
Remember, whenever we are multiplying two numbers with the same base and with different exponents, we should always add the exponents and keeps the same base.
In this ,case it is, -6 and -1.
-6 + (-1) = -7
So the answer would be 6^(-7).
