Answer: 144
Step-by-step explanation: The problem shown here can be read as "10 to the 2nd," oe "12 to the 2nd power."
The 12 is called the base and the 2 that is raised up is called the exponent.
The exponent of 2 tells us that we multiply our base 2 times.
So we have 12 · 12 which is 144.
The numbers that we multiply together are called factors so in this problem, we have 2 factors of 12.

Answer: 5</h3>
=================================================
Work Shown:
x^2 - 5x + 1 = 0
x^2 + 1 - 5x = 0
x^2 + 1 = 5x
(x^2 + 1)/x = 5 .... where x is nonzero
(x^2)/x + (1/x) = 5
x + (1/x) = 5
---------------
An alternative method involves solving the original equation using the quadratic formula. After you get the two roots x = p and x = q, you should be able to find that p + 1/p = 5 and also q + 1/q = 5 as well.
In this case,
p = (5 + sqrt(21))/2
q = (5 - sqrt(21))/2
