When bases are same powers are equal?
If we multiply two exponents with the same base then their powers will add. If we divide two exponents with the same base then their powers will subtract.
How do you combine exponents with the same base?
For numbers with the same base and negative exponents, we just add the exponents. In general: a -n x a -m = a –(n + m) = 1 / a n + m. Similarly, if the bases are different and the exponents are same, we first multiply the bases and use the exponent.
What is it called when two things are multiplied together?
The result of a multiplication operation is called a product. The multiplication of whole numbers may be thought of as a repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier.
Can you multiply powers with different bases?
It is possible to multiply exponents with different bases, but there’s one important catch: the exponents have to be the same. First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same.
Can you multiply exponents with different powers?
When the exponents with different bases and different powers are multiplied, each exponent is evaluated separately and then multiplied. It can be written mathematically as an × bm = (an) × (bm).
What are the first 10 powers of 2?

What happens when you add exponents with the same base?
To multiply terms with the same base, keep the same base and add the powers together. To multiply terms with different bases but the same power, raise the product of the bases to the power. This can be expressed as: If the exponents have coefficients attached to their bases, multiply the coefficients together.
How do you multiply in different bases?
When we multiply numbers in other bases, we can do it two ways: First method: Convert both numbers to base 10, multiply them normally, then convert that back to the desired base. This is usually preferable when multiplying numbers of different bases.
How do you divide exponents with different bases?
Dividing exponents with different bases. When the bases are different and the exponents of a and b are the same, we can divide a and b first: a n / b n = (a / b) n. Example: 6 3 / 2 3 = (6/2) 3 = 3 3 = 3⋅3⋅3 = 27. When the bases and the exponents are different we have to calculate each exponent and then divide: a n / b m. Example:
What tells you how many times to multiply the base together?
An exponent is a small, superscripted number written above and to the right of a larger number, the base — this tells you how many times you multiply the base by itself. This repeated multiplication is commonly referred to as the base value being “raised to the power of” the exponential value.
How do you multiply powers with the same base?
To multiply powers of the same base, add the exponents together: If there’s more than one base in an expression with powers, you can combine the numbers with the same bases, find the values, and then write them all together.
What to do with exponents when multiplying?
When multiplying exponents, if the exponents are positive, you add them together. If the exponents are negative, you subtract. The rules are the same as adding and subtracting integers. However, you can only combine exponents if the base is the same (i.e., 2^4 and 2^7 multiplied 2^4 * 2^7 = 2^11).
