Answer:
- as written: 352
- as perhaps intended: 22
Explanation:
When you ask for evaluation of a math expression, you need to write what you mean.
Here, the order of operations requires you compute the exponentials before you do the division or addition:
9 ^ 3/2 - 25 ^ 1/2 = (9^3)/2 -(25^1)/2
= 729/2 -25/2 = 364.5 -12.5 = 352
__
It seems quite likely that you intend the exponents to be 3/2 and 1/2. In that case, parentheses are required.
9 ^ (3/2) - 25 ^ (1/2) = 27 -5 = 22
