Answer:
The √125 can be factored out to 25 and 5 then 25 can be factored out to 5 and 5. Then you pair up the numbers, you have a pair of 5's and a 5 left over. So the pair of 5's goes inside the radical as √5 and on the outside of the radical you have 5×3. So 3√125≈15√5.

Proofs
Step-by-step explanation:





They are not inverse because f^-1(x) = x - 3/2 is not the inverse to g(x) = 2x - 3.
For this case we have that by definition, a function is of the form:

So, we have the following system of equations:

Equating the equations we have:

Adding 2x to both sides of the equation:

Subtracting 2 from both sides of the equation:

Dividing between -4 on both sides of the equation:

Thus, the value of the variable "x" is -0.5.
Answer:
-0.5
