When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
How do you divide exponents?
Dividing exponents is just subtracting the numerator exponent and the denominator exponent. For example, 3^4 / 3^2 = 3^2. *The division sign is just like a giant subtraction sign** That will help you to remember this rule. So how about x^12 / x^5? its x^7!
How do you turn a negative exponent into a positive exponent?
Move the base number to the 'other side" of a division bar and change the exponent to the opposite sign. Example: 1/9 = 3^-2 becomes 1/(3^2) or 4 = 1/ (2^-2) becomes 2^2. Try it on your calculator to check your work.
What is the additive of -4?
If you mean the ADDITIVE INVERSE, change the minus sign to a plus sign. (And if you see a plus sign, you change it to a minus sign.)
What is an example of a quadratic expression?
x2 + 3x + 4 This is quadratic because the highest exponent of x is 2, and it is an expression because there is no equals sign.
What is the rule which allows us to change the sign of an exponent is called?
The rule that allows us to change the sign of an exponent is called the "negative exponent rule." This rule states that for any non-zero number ( a ) and integer ( n ), ( a^{-n} = \frac{1}{a^n} ). Essentially, a negative exponent indicates the reciprocal of the base raised to the absolute value of the exponent.
When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
What is the rule for adding two numbers whose sign are alike?
The sign doesn't change.

What if the problem is a fraction with a negative exponent?
Flip the fraction top-to-bottom, and delete the minus sign from the exponent.
How do you turn a negative exponent into a positive exponent?
Move the base number to the 'other side" of a division bar and change the exponent to the opposite sign. Example: 1/9 = 3^-2 becomes 1/(3^2) or 4 = 1/ (2^-2) becomes 2^2. Try it on your calculator to check your work.
What does the exponent mean in scientific notation?
The exponent is an unknown variable. It is a variable because it will change into a known number when we get further into the equation. Take this for example. 4x=8 - where x is the exponent. To work out the problem we simply move the 4 over the equal's sign. Since it is 4x, this means that it is 4 times x. Since we are moving the 4 over the equals sign, we have to change the multiplication, into a division. x=8/4 which equals 2. The x is a 2. To check, we we substitute the 2 with the x in the equation. 4x2=8, which is correct.
How do you type the exponent sign from the keyboard?
shift then 6 at the same time
Is a exponent a number with a plus or - sign?
You fail SO badly. If we have x^4, the 4 is the exponent- the power to which a number is raised. It can be positive or negative.
How do you predict whether a power will be negative or positive?
To predict whether a power will be negative or positive, examine the base and the exponent. If the base is positive, any exponent—whether positive or negative—will yield a positive result. Conversely, if the base is negative, an even exponent results in a positive value, while an odd exponent produces a negative value. Thus, the sign of the power depends on both the sign of the base and whether the exponent is odd or even.
What is a square unit sign?
The exponent "2" as in a number squared, e.g. cm2 or in2
What determines the sign of the exponent when a number is written in scientific notation?
The sign of the exponent for a number written in scientific notation depends on whether it is a whole number or a fraction. 40 is 4 x 101 0.4 is 4 x 10-1
