Answer:
1. 15625
2. 256
3. 46656
Step-by-step explanation:
Simplify the following:
(5^3)^2
Multiply exponents. (5^3)^2 = 5^(3×2):
5^(3×2)
3×2 = 6:
5^6
5^6 = (5^3)^2 = (5×5^2)^2:
(5×5^2)^2
5^2 = 25:
(5×25)^2
5×25 = 125:
125^2

Simplify the following:
(4^2)^2
Multiply exponents. (4^2)^2 = 4^(2×2):
4^(2×2)
2×2 = 4:
4^4
4^4 = (4^2)^2:

Simplify the following:
(6^2)^3
Multiply exponents. (6^2)^3 = 6^(2×3):
6^(2×3)
2×3 = 6:
6^6
6^6 = (6^3)^2 = (6×6^2)^2:
(6×6^2)^2
6^2 = 36:
(6×36)^2
6×36 = 216:
