Answer:

3\sqrt7

Step-by-step explanation:

This is because you can split 63 into two numbers, \sqrt{9} and \sqrt{7}. When you simplify \sqrt{9} turns into 3 but \sqrt{7} will not simplify further so it will be 3\sqrt{7}.

Endpoint: (1,7), midpoint: (-10,10)
algol [13]

The answer is (-21, 13) for The second endpoint.  

Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Kx + Lx)/2 = Mx

(Kx + 1)/2 = -10

Kx + 1 = -20

Kx = -21

And now we do the same thing for y values

(Ky + Ly)/2 = My

(Ky + 7)/2 = 10

Ky + 7 = 20

Ky = 13

This gives us the final point of (-21, 13)

[(2x)^x (2x)^2x]^1/x<br>how do you simplify this?
Monica [59]
Note that [ (2x)^x ]^(1/x) = 2x, and that [ (2x)^(2x) ]^(1/x) = (2x)^2 = 4x^2

Multiplying these 2 results together, we get (2x)(4x^2) = 8x^3 (answer)
