Oh, what a happy little question! To write 21 as a power, we can express it as 3 to the power of 2, because 3 multiplied by itself twice equals 9, and then 9 multiplied by 3 again equals 21. Just like painting a beautiful landscape, expressing numbers as powers can bring a sense of harmony and balance to our mathematical creations.

No it's not 21 because 3 x 3 is 9 x 3 is 27

To write 21 as a power, we need to express it in terms of a base raised to an exponent. One way to write 21 as a power is 3^1 x 7^1, as 21 can be expressed as the product of the prime factors 3 and 7. Another way is 21^1, as any number raised to the power of 1 is the number itself.

Oh, dude, writing 21 as a power is like finding the square root of a pineapple. It's 21 to the power of 1, because anything to the power of 1 is just itself. So, yeah, 21 as a power is just 21. Cool, right?
