X^2=-5 solve for x. write your answer in simplified, rationalized form

x = 1.236 i

x = i √5

Step-by-step explanation:

Here in this question we are given the equation x² = - 5, which we have to solve.

Since x² = - 5  

⇒ x = √ (- 5).

Now, √(-5) can be written as .

Now, it is considered an imaginary number, not real number when there is a square root of a negative number.

Therefore, √(- 1) is an imaginary number and it is denoted by i.

Therefore, x = i √5 .... this is the solution in rationalized form.

Again, x = 1.236 i ...... this is the solution in simplified form. (Answer)

the answer will be

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
