Answer:
n = -21/4 <em>or </em>-5.25
Step-by-step explanation:
The square root of 81 is 9
Your answer is <em>9
</em>Work:
9 x 9 = 81
You could factor it as 2(x + 3)
The denominator of the raised fraction is what goes on the outside of the square root. So if you had 2 raised to 1/3, you'd put the 3 raised outside to the left of the radical and the 2 inside. They give the same answer, so if you know one, you can always play with the other until you get the same answer. My teacher told us in Calculus a funny/weird way to remember it is the "bottom (of the raised fraction) goes in the crack (of the radical)." Does this help??
