Which expression is equivalent to 3√x10

Mathematics

Answer: 3x^5

Explanation

sqrt(x^10) is x^5 since the power of x is 10 and the square root is of degree 2, so 10/2 = 5 and x^5 will be the new power of x after the square root. Hence, 3x^5.

Hope this helps :)

B is the midpoint of AC. If AB= X +5 and BC = 2X -11, find the measure of AB
Murljashka [212]
First, you know that B is the mid point, meaning AB is equal to BC. Therefore, you can set up the equation: x+5=2x-11. Then, you solve for x. Once you are done solving, you should get 16. Hope this helps!

Prove that the value of the expression does not depend on the variable x:
Leviafan [203]

Answer:

See below

Step-by-step explanation:

If an expression is not dependent on x, it simplified form must not contain x. To show that this is the case for (a) and (b) we need to simplify them and assess:

(a)

(x-5)(x+8)-(x+4)(x-1)=\\=x^2-5x+8x-40-x^2-4x+x+4=-36

Indeed, does not depend on x!

And (b)

x^4-(x^2-1)(x^2+1)=x^4-x^4+x^2-x^2+1=1

Again, does not depend on x.
