We can use the fact that 32 is equal to 2 raised to the power of 5:

32 = 2^5

Substituting this into the equation gives:

16^x = 2^5

We can then rewrite 16 as 2^4, since 16 is equal to 2 raised to the power of 4:

(2^4)^x = 2^5

Simplifying the left side of the equation gives:

2^(4x) = 2^5

Now we can see that the bases of both sides of the equation are equal, so we can set the exponents equal to each other:

4x = 5

Dividing both sides by 4 gives:

x = 5/4

Therefore, the solution to the equation 16^x = 32 is x = 5/4.
