Step-by-step explanation:
to the power to the power of - we multiply the powers.
(2³)⁴ = 2¹²
as this is the same as
2³ × 2³ × 2³ × 2³
so, the power is 4×3 = 12
to the power of times to the power of times to the power of ... - we add the powers (if the base is the same).
2²×2²×2²×2²×2² = 2¹⁰
the power is 2+2+2+2+2 or 5×2 = 10
