Simplifying Complex Expressions That Contain Square Roots from Chapter 21/ Lesson 3 12K Complex expressions with square roots can be simplified by using the letter 'i' to represent the square root of a negative number. Discover complex expressions, imaginary numbers, and how to simplify complex exp...
In general terms, if aa is a positive real number, then the square root of aa is a number that, when multiplied by itself, gives aa. The square root could be positive or negative because multiplying two negative numbers gives a positive number. The principal square root is the nonnegative...
Since a square root has two values, one positive and the other negative y2- 11y - 12 = 0 has two solutions: y = 11/2 + √169/4 or y = 11/2 - √169/4 Note that√169/4can be written as √169/ √4which is13 / 2
log(x) + log(y) == log(x*y) if both are not negative a*log(x) == log(x**a) if x is positive and a is real If force is True then the assumptions above will be assumed to hold if there is no assumption already in place on a quantity. For example, if a is imaginary or...

If x2 = y, then x is a square root of y. From this definition we have seen that every positive number has two square roots, one positive and one negative. Recall these definitions from chapter 7. The principal square root of a positive number is the positive square root. The symbol ...

Complex numbers are defined by their inclusion of the i term, which is the square root of minus one. In basic-level mathematics, square roots of negative numbers don't really exist, but they occasionally show up in algebra problems. The general form for a complex number shows their...
