Answer:
6^-2
Step-by-step explanation:
To answer this, you need to know one basic law of indices:
x^-n = 1/x^n
So here 1/36 is the same as 36^-1.
Then we can simply sqr root 36 to give (6^2)^-1.
When two powers are one in and one out of the brackets, they multiply each other. So here it would be 2*-1, which would give -2.
So the answer is 6^-2.
