When you use PEMDAS, this would be very easy. Just the others:

Parenthesis(no parenthesis in this expression, so it should be crossed out.)
Exponents (no exponents in this expression, so it should be crossed out)
Multiplication (Yes)
Division (no division in this expression, so it should be crossed out.)
Addition (Yes.)
Subtraction (no subtraction in this expression, so it should be crossed out)

Therefore,

 
4 + 2 • 8

= 20.

There is a difference of 14 units between -2 and 12. To find the coordinate in the middle, just add 7, half the distance between -2 and 12, to -2 and subtract 7 from 12. That gives you the coordinate 5.

What is 1/x∧-3/6 and how do you get to that answer?
Black_prince [1.1K]

Answer:

x^\frac{1}{2}

or

\sqrt{x}

Step-by-step explanation:

\frac{1}{x^\frac{-3}{6}}

I'm going to reduce -3/6 to -1/2 by dividing top and bottom of -3/6 by 3.

\frac{1}{x^\frac{-1}{2}}

Now I'm going to get rid of the negative exponent by moving x to the top; so -1/2 will change to 1/2 instead when doing this:

1x^\frac{1}{2}

x^\frac{1}{2}

\sqrt{x}

Please let know if I read the problem right:

\frac{1}{x^\frac{-3}{6}}
