I think it's 92
± 3 to the fourth power equals 81.
3 to the power of 4 = 81
92, 34, or 81 * 100.
81/10
9 to the second power :))
9 to the 2nd power (92) 3 to the 4th power (34)
92 = 81 AND 3^4
3 to the power of 4 9 to the power of 2 81 to the power of 1 I'm on this problem in my notebook too ;)

81 is a whole number whose simplest form is 81.
3 tho the fourth power is 81 (3x3x3x3= 9x3x3 = 27x3 = 81)
To find the number that 81 is 90% of, you can set up the equation 0.90x = 81, where x is the unknown number. To solve for x, divide both sides by 0.90 to isolate x, giving you x = 81 / 0.90. Therefore, 81 is 90% of 90.
92, 34, or 81 * 100.
81. Each number is the previous number times three. 3 x 27 = 81.
