The missing base of 81= ^2

the correct answer is 9²

9

Step-by-step explanation:

It is stating that 81 is equal to x², in which the variable x stands for a number.

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by rooting both sides:

√x² = √81

x = √81 = √(9 * 9) = 9

9 is your missing base.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
