Answer:
20 cm is the length of third side of triangle
Step-by-step explanation:
Length of 1st side = a
Length of 2nd side = 10cm = b
Length of 3rd side = 15cm = c
So,
Perimeter of triangle = 45 cm
a+b+c = 45cm
a + 10 + 15 = 45 cm
.'. a = 45-25 cm
= 20 cm
We just have to evaluate and compare the numbers:

So, the only expression that exceeds 4^3 is (-3)^4
