21 to the 2nd power is 441.
42 + 5 = 16 + 5 = 21
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
91 to the 2nd power is 8,281.
2121 = 5.842587018*1027
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.
42 + 5 = 16 + 5 = 21
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
2-21 power = -19
91 to the 2nd power is 8,281.
4 to the 2nd power in exponents is 42
