## How to Simplify Exponents

Multiply exponents by adding the exponents together. For example, x to the fifth power multiplied by x to the fourtth power equals x to the ninth power (x5 + x4 = x9), or (xxxxx)(xxxx) = (xxxxxxxxx).

Divide exponents by subtracting the exponents from each other. The equation x to the ninth power divided by x to the fifth power simplifies to x to the fourth power (x9 – x5 = x4), or (xxxxxxxxx)/(xxxxx) = (xxxx).

Simplify an exponent raised to another power by multiplying the exponents together. Simplifying x to the third power raised to the fourth power produces x to the 12th power [(x3)4 = x12], or (xxx)(xxx)(xxx)(xxx) = (xxxxxxxxxxxx).

Remember that any number to the 0th power equals one, meaning x to any power raised to the 0th power simplifies to one. Examples include x0 = 1, (x4)0 = 1, and (x5y3)0 = 1.

Note that equations with different variables such as x squared multiplied by y cubed (x2y3) cannot be combined to produce xy to the sixth power. This equation is already simplified. However, if the entire equation of x squared multiplied by y cubed is then squared, each of the variables is simplified separately, resulting in x to the fourth power multiplied by y to the sixth power (x2y3)2 = x4y6, or (xxxx)(yyyyyy).

Hi,

for x<0,
|x-1| = 1-x
$$\sqrt{1-(x + 1) |x-1|}$$
=$$\sqrt{1-(x + 1)(1-x)}$$
=$$\sqrt{+x^2}$$
=$$\sqrt{x^2}$$
=|x|, again x<0
= -x

Hi!

I'm confused as why the answer isn't simply x (as opposed to-x). The absolute value of x, when simplified, is positive x, even if it is stated that x<0. Why do you go back and add a negative?

Thanks![/quote]

What is positive xwhen x is negative? What do you mean by absolute value of x, when simplified?
Is $$|-7| = -7?$$ NOOOO! $$|-7|=-(-7)=7>0!!!$$
Absolute value is always non-negative.[/quote]

Hi EvaJager,

First, many thanks for the help you give me and others on this board. It is much appreciated.

Here is where my answer differed from yours. When I solved it, I reached this point:

= |x|
= x

Here is what you did:

= |x|
= -x

I am confused why you said the absolute value of x is -x. I thought all the absolute value of all numbers is non-negative.

Thanks again!

I am asking the same question again: if $$x = -7,$$ is $$|-7|=-7$$??? NO!!!
$$|-7| = 7$$. But $$x$$ is not $$7, \,\,x$$ is  What is the connection between $$-7$$ and $$7?$$
Simply, $$7 = -(-7).$$
When $$x$$ is negative, multiplying it by $$-1$$ it turns it into a positive number. Therefore, $$|x|=-x$$ for $$x<0.$$
You cannot write $$|-7|=$$ A letter denoting a number if doesn't have a minus sign in front of it, it doesn't mean it cannot be negative. $$x$$ doesn't automatically designate a positive number. You are stating yourself that $$x$$ is negative!

Absolute value of a number expresses the distance on the number line between that number and 0. Distance between $$-7$$ and $$0$$ is $$7$$.
A number $$x$$ can be negative, for example $$x=-7$$. And $$-x$$ can be positive, if $$x=-5$$, because $$-(-5)=5.$$
