What is 4 raised to the fourth power mean?

Answer 1

Raising a number to a positive integer power is pretty straightforward. Take the number and multiply it by itself a number of times. So 4² = 4 x 4 = 16. It is taken 2 times then multiplied. 4³ = 4 x 4 x 4 = 64. The number is taken 3 times and multiplied. This is also called 4 cubed or 4 raised to the third power. 4 raised to the fourth power is 4^4 = 4 x 4 x 4 x 4 = 256. The carat symbol [^] is often used to designate raising to a power.

Answer 2

It means four multiplied by itself four times (4 x 4 x 4 x 4 or 256).
