The process of integration calculates the integrals. √a x √b = √ (a x b) Show more.It is an algebraic number, and therefore not a transcendental number. If you ever need to calculate sqrt of -1 is because you are solving x 2 + 1 = 0, and such equation will always have two different solutions which are at the same "level". The square root expressions √5a, 4√3xy 5, and 11m2n√a − 4 2x2 are in simplified form.Technically, it should be called the principal square root of 2, to distinguish it from the negative number with the same property. If the angle is expressed in radians as , this takes care of the case where a is 1 and b is 2, 3, 4, or 6. The inverse hyperbolic functions are multiple-valued and as in the case of inverse trigonometric functions we restrict ourselves to principal values for which they can be considered as single-valued. My question, however, has to do with simplifying this answer using trig. In this event, $\sqrt{-1} = i$ for the continuous branch of square root that satisfies $\sqrt{1} = 1$.
