1 divided by a number with an exponent is the same as the number to the exponent of opposite sign. For example 1 divided by 2 to the third power is the same as 2 to the minus 3 power

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 find a reciprocal of a number with an exponent?
You change the sign of the exponent. For example, the reciprocal of 2 to the power 8 is 2 to the power -8. Alternately, you can change the whole expression to the denominator. In this case, the reciprocal of 2 to the power 8 is 1 divided by (2 to the power 8).
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.
Additive inverse of -12?
Additive inverse means that you are supposed to change the sign:* If there is a plus sign (or no sign at all), change it to a minus. * If there is a minus sign (as in this case), change it to a plus (or no sign).

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.
Rule for 180 degree clockwise rotation?
change the sign, but DONT switch the coordinates (:

How do you type the exponent sign from the keyboard?
shift then 6 at the same time
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.
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.
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
