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.

This is best written as 1021, since it is such a large number. If you want to write it out, write a one, followed by 21 zeroes.This is best written as 1021, since it is such a large number.

245 = 2.45 × 102
You would write it as 10 to the 11th power multiplied by 9.99.
You would write it like this 21 or 2.1*10^1.

0.42 = 21/50
7/12
It would be 106
2.2 = 21/5 or 11/5
You would write it as 10 to the 11th power multiplied by 9.99.
