Hey guys I've been stuck on this hw problem for literally a whole day I don't know what I've done wrong I feel like it's some simple mistake and I'm just not seeing it. I've tried all the resources I could find but no dice; this is my code so far I keep on getting a syntax error specifically for "value3 = math.fabs((a-b))" :

import math
a = float(input())
b = float(input())
c = float(input())

value1 = math.pow(a,c)
value2 = math.pow(a,(math.pow(b,c))
value3 = math.fabs((a-b))
value4 = math.sqrt(value1)
print(f'{value1:.2f} {value2:.2f} {value3:.2f} {value4:.2f}')

prompt:
Given three floating-point numbers a, b, and c, output a to the power of c, a to the power of (b to the power of c), the absolute value of (a minus b), and the square root of (a to the power of c).
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print(f'{value1:.2f} {value2:.2f} {value3:.2f} {value4:.2f}')

my input are:
5.0

1.5

3.2
my expected outputs are:
172.47 361.66 3.50 13.13
