Simplify. Identify any x value for which the expression is undefined x^2+3x/x^3

x = 0

Step-by-step explanation:

I think you mean

The only undefined values of x come from the denominator, x^3.

A denominator cannot equal zero since division by zero is undefined.

Therefore if x^3 equals zero, you get an un defined expression.

We let x^3 = 0 and solve for x to find the values of x that would cause an undefined expression.

x^3 = 0

Solve for x by taking the cubic root of both sides.

x = 0

x = 0

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
