<span>You need two number lines to compare two fractions when their denominators are different. The procedure is that you draw to segment lines of the same length but divede each line according to its denominator and then compare the place of the points that mark the fraction numbers, the line that content the marke further away from the start end will be indicate the greater fraction. For example, the fractions 3/4 and 7/10. One line will be divided inot 4 equidistant segments, and the other with 10 equidistant segments. The fraction 3/4 will be represented with 3 marks on the first line, and the fraction 7/10 will be represented with 7 marks on the second line. Now you can compare the size of the two segments marked adn decide which fraction is greater. </span>

$i^5+i^{-25}+i^{45}$<img src="https://tex.z-dn.net/?f=%24i%5E5%2Bi%5E%7B-25%7D%2Bi%5E%7B45%7D%24" id="TexFormula1" title="$i^5+i
gregori [183]

i^5+i^{-25}+i^{45}

Rewrite the term i^{-25}

=i^5+\dfrac{1}{i^{25}}+i^{45}

Expand each term so we have

=i(i^2)^2+\dfrac{1}{i(i^2)^{12}}+i(i^2)^{22}

Use the fact that i^2=-1

=i(-1)^2+\dfrac{1}{i(-1)^{12}}+i(-1)^{22}

Use the fact that (-1)^{a}=1 when a is an even number

=i+\dfrac{1}{i}+i

Simplify

=i-i+i

=i

Let me know if you need any clarifications, thanks!

How do you use the properties of exponents and logarithms to rewrite functions in equivalent forms and solve equations
Leona [35]
Exponential:
 
It is called the exponential function of base a, to that whose generic form is f (x) = a ^ x, being a positive number other than 1.
 Every exponential function of the form f (x) = a^x, complies with the followingProperties:
 1. The function applied to the zero value is always equal to 1: f (0) = a ^ 0  = 1
 2. The exponential function of 1 is always equal to the base: f (1) = a ^ 1  = a.
 3. The exponential function of a sum of values is equal to the product of the application of said function on each value separately.
 f (m + n) = a ^ (m + n) = a ^ m · a ^ n
 = f (m) · f (n).
 4. The exponential function of a subtraction is equal to the quotient of its application to the minuend divided by the application to the subtrahend:
 f (p - q) = a ^ (p - q) = a ^ p / a ^ q
 Logarithm:
 
In the loga (b), a is called the base of the logarithm and b is called an argument, with a and b positive.
 Therefore, the definition of logarithm is:
 loga b = n ---> a ^ n = b (a> 0, b> 0)

Describe how to transform the graph of f into the graph of g. (2 points)
Zigmanuir [339]

:

f into the graph of g. f(x) = x4 and g(x) = -(-x)4 ... y = f(-x) is a y-axis reflection (here the negative sign is "inside" the function) ... on the same axis sketch the graphs of y=x2-3, and the graph of y=2x ... find the equation of the horizontal line passing through the points (-2,3).
