Chapter 0: Problem 5

Evaluate each expression or indicate that the root is not a real number. $$\sqrt{-36}$$

Short Answer

Expert verified
The square root of \(-36\) is not a real number. However, in the complex number system, it is \(6i\).

Step by step solution

01

Identify the Type of Number

Identify the given number as negative. In this case, it is -36.
02

Try to Evaluate the Square Root

Attempt to calculate the square root of the number. But since the given number is negative, its square root cannot be calculated using the standard method because a negative number does not have a real square root.
03

State the Result

The square root of \(-36\) does not exist in the real number system. It's a complex number, and if we allow for complex numbers, the square root of \(-36\) would be \(6i\) where \(i\) is the imaginary unit.

Simplify using properties of exponents. $$\left(25 x^{4} y^{6}\right)^{\frac{1}{2}}$$

The early Greeks believed that the most pleasing of all rectangles were golden rectangles, whose ratio of width to height is $$\frac{w}{h}=\frac{2}{\sqrt{5}-1}$$ The Parthenon at Athens fits into a golden rectangle once the triangular pediment is reconstructed. (IMAGE CANT COPY) Rationalize the denominator of the golden ratio. Then use a calculator and find the ratio of width to height, correct to the nearest hundredth, in golden rectangles.
