A negative exponent is equivalent to the reciprocal of the number with a positive exponent.3^2 = 9.

The reciprocal of 3^2 = 1/9.

Therefore 3^-2 = 1/9.

Meanning of positive exponent?

An exponent is the power that a number is raised to. For instance, in the expression 3^2 ("three squared"), 2 is the "exponent" and 3 is the "base." A positive exponent just means that the power is a positive number. For instance, the following expression does not involve a positive exponent: 3^(-2). Horses rule!!!!!

How do you solve when you have a negative exponent?

A negative exponent is the same as 1/(the positive exponent). For example, 2^3 is (2*2*2) = 8. 2^(-3) is 1/(2*2*2) = 1/8. So, just calculate the positive exponent version, and put it under 1.

How do you determine the exponent when rewriting an expression of repeated multiplication in exponential form?

The exponent for a factor is the number of times that the factor appras in the multiplication. An exponent of 1 is not usually written out. So, 2*2*2*3*3*3*3*5 = 23*34*5

What is an exponent what does it tell you to do?

An exponent is a superscripted number or value (2x+3, 7, 4, -3, etc) that tells you how many times to multiply an item by itself. For example, 24 (2 with an exponent of 4) is 2 x 2 x 2 x 2, or 16.

What is an integral exponent?

If you have a real number,a, and raise it to a power b we say a^b is a times itself b times. That is to say aaaaaaaa...aaa b times. a is the base and b is the exponent. So if b is an integer,... -3,-2,-1,0,1,2,3... ,then we have an integral exponent. Examples are 2^5 and 2^-3. An example that is NOT an integral exponent is 2^(1/2) since 1/2 is not an integer. Dr. ChuckIt means that the exponent is a whole number, for example 3, 0, or -5.


What is the meaning of base and exponent?

If we consider 2 raised to the power 3 i.e.,2^3, then the number 2 is called the BASE and 3 is called the EXPONENT IT means 2 is multiplied to itself 3 times

Why is do you use a 2 for the meaning of squared?

The reason you use 2 for the exponent when saying a number squared is because you are taking the number with the exponent of 2 and multiplying it by itself. 2^2 = 4 since 2 x 2 = 4. After squared is cubed for an exponent of 3, 2^3 = 8, since 2 x 2 x 2 = 8.


What is a fractional exponent?

That means that the exponent is a fraction, such as 21/2 = square root of 2, 101/3 = cubic root of 10, etc.
