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.
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 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.)

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.

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.
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
How can the decimal number 175.23 be represented as a sign mantissa and exponent?
To represent the decimal number 175.23 in sign mantissa and exponent form, we first need to convert it into scientific notation. This number can be written as 1.7523 x 10^2. The sign of the mantissa will be positive since the original number is positive. The mantissa will be 1.7523, and the exponent will be 2. Therefore, the representation would be (+1.7523, 2).
How can you tell if an exponential function is exponential growth or decay by looking at its base?
It is not enough to look at the base. This is because a^x is the same as (1/a)^-x : the key is therefore a combination of the base and the sign of the exponent.0 < base < 1, exponent < 0 : growth0 < base < 1, exponent > 0 : decaybase > 1, exponent < 0 : decaybase > 1, exponent > 0 : growth.
