We know how to find the square root of any positive real number. In a similar way, we can find the square root of a negative number. The difference is that the root is not real. If the value in the radicand is negative, the root is said to be an imaginary num...

Square Root of a Negative Real Number (Imaginary Numbers): SMART Board Resource for Algebra 2 (Grades 6-12) (eLesson Plan)
To calculate square root of a number in A2, use this one: =SQRT(A2) If a number is negative, like in rows 7 and 8 in the screenshot above, the Excel SQRT function returns the#NUM! error. It happens because the square root of a negative number does not exist among the set of rea...
How do you find the square root of a negative number like -5? Complex Numbers: Numbers that cannot be represented on a number line are called complex numbers. {eq}\pi{/eq} is not a complex number because even though it is an unending decimal, we can still represent it on a number ...
Why can't polynomials have negative exponents? Why does a number raised to the zero power equal one? Derive the formula sinh^(-1) x = ln (x + sqrt(x^2 + 1)) for all real x. Explain in your derivation why the plus sign is used with the square root instead of the minus sign....

Step 1:Rewrite all square roots of negative numbers,−a, asa⋅−1, whereais positive. We need to rewrite the square root of negative 28. This gives us: 20⋅−28=20⋅28⋅−1 Step 2:Fully simplify all square roots in the problem. Use the fact that−1=i. ...
. There, we explain how to compute the derivative of a square root; we also elaborate on how to calculate the square roots of exponents or fractions. Finally, if you are persistent enough, you will find out that it is, in fact, possible to obtain the square root of a negative number....
