1. What is extraneous solutions? 2. What does the numerator of a fractional exponent mean?
3. What is the complex number?

see explanation

Step-by-step explanation:

1

An extraneous solution tend to occur when dealing with equations involving radicals or absolute value functions.

Solutions are obtained by solving the equation and then must be verified by substituting them into the original equation.

Although a simplified solution is obtained it may not satisfy the original equation and is therefor extraneous.

2

It is the power that the value is being raised to

For example

rule of exponents

⇔

3

A complex number does not appear on the set of real numbers.

It is composed of a real part and an imaginary part, usually in the form

z = a + bi ( where a and b are real )

a is the real part and bi the imaginary part

They are based on = i

We can then solve problems involving negative radicals, particularly in solving quadratic equations

x = ± = ± = ± × = ± 4i

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
