By addition. Exponents are multiplied by adding them together. Example:
22 = 4 = (2x2)
23 = 8= (2x2x2)
If we multiply 22 x 23 we get (2x2) x (2x2x2) = 4 x 8 = 32
or 22 x 23 = 25 = (2x2) x (2x2x2) = (2x2x2x2x2) = 25 = 32
Same with negative exponents: (A negative exponent indicates a reciprocal (1/x))
2-2 = 1/4 (1/2 x 1/2)
2-3 = 1/8 (1/2 x 1/2 x 1/2)
2-2 x 2-3 = 1/4 x 1/8 = 1/32
2-2 x 2-3 = (1/2 x 1/2) x (1/2 x 1/2 x 1/2) = (1/2 x 1/2 x 1/2 x 1/2 x 1/2) = 2(-2)+(-3) = 2-5 = 32
Hope this helps.

Can you have negative exponents in the denominator?
You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
When you have two different exponents do you add them or multiply them?
Multiply
How do you divide a positive power of ten by a negative power of ten?
You reverse the sign of the power and multiply by adding exponents. Example 10 to the 7 divided by 10 to the negative 6 = 10 to the 13
How do you change powers with negative exponents to powers with positive exponents?
by doing reciprocal
How do you solve negative exponents and zero exponents?
Anything with a zero exponent is 1. Positive exponents tell how many times to multiply a base number. Negative exponents tell how many times to divide a base number. Negative exponents are the reciprocals of positive ones. 10^2 = 100 10^1 = 10 10^0 = 1 10^-1 = 1/10 10^-2 = 1/100 3^2 = 9 3^1 = 3 3^0 = 1 3^-1 = 1/3 3^-2 = 1/9
How do you multiply negative exponents outside of a parenthesi?
just add them together
How do you simplify negative numbers with positive exponents?
If the exponent is an even number you can drop the negative, because is you were to multiply it out the negatives would cancel out.
Can you have negative exponents in the denominator?
You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
When you raise a power to a power what do you do with the exponents?
You multiply the exponents.
How do you do exponential notation with negative exponents?
How to write them? ten to the minus three is 10^-3How to multiply them? add the exponents. Ex: 10^-3 x 10^-4 = 10^-7
How do you raise a power to a power?
The rule is that you multiply the exponents. So if I have 2 squared and I want to raise it to the third power, you multiply the 2x3=6. When you multiply powers you add the exponents. When you raise exponents to a power you multiply. This works for rational exponents which can be used to represent roots as well.
When you have two different exponents do you add them or multiply them?
Multiply
How do you multiply numbers when it has exponents?
You should multiply the numbers, but add the exponents. For example: 92 x 27 = 189
When you are multiplying exponents do you only add the exponents or do you also multiply the bases?
Add the exponents
Why do you have negative exponents?
Negative exponents are used to represent 1 divided by an a base to a specific exponent.
When do you know to add exponents and when to multiply exponents?
You cannot add exponents, you can only multiply. Example 3^3 it would be 3x3x3 9^3 it would be 9x9x9
The exponents in the terms of a polynomial must be?
why the exponents can not be negative
