Yes, you can subtract the exponents, for example 5^3/5^2 = 5^3-2 = 5^1
Thats the same as 125/25 = 5

What are the laws of exponents for division?
If the base is the same, you can subtract the exponents. For example (using "^" por powers):10^5 / 10^2 = 10^310^5 / 10^(-4) = 10^9
What is x to the fifth power times x to the third power?
Use the properties of powers. In this case, you can combine powers with the same base, by simply adding the exponents.
What are rules of adding subtracting dividing multiplying scientific notation?
Addition and Subtraction in Scientific NotationA number written in scientific notation is written as the product of a number between 1 and 10 and a number that is a power of 10. That is, it is written as a quantity whose coefficient is between 1 and 10 and whose base is 10.Addition and SubtractionOne of the properties of quantities with exponents is that numbers with exponents can be added and subtracted only when they have the same base and exponent. Since all numbers in scientific notation have the same base (10), we need only worry about the exponents. To be added or subtracted, two numbers in scientific notation must be manipulated so that their bases have the same exponent--this will ensure that corresponding digits in their coefficients have the same place value.Multiplying a number by another number with the same base is equivalent to multiplying their coefficients and adding their exponents. Therefore, if we want to add two quantities written in scientific notation whose exponents do not match, we can simply write one of the powers of 10 as the product of two smaller powers of 10 , one of which agrees with the other term.Alternately, if we want to preserve the exponent of the term with the larger power of 10 , we can simultaneously multiply and divide the other term by a power of 10 , applying the rule for multiplication of exponents in one case and dividing the coefficient in the other. It is this procedure that we outline below. Once the numbers have the same base and exponents, we can add or subtract their coefficients.Here are the steps to adding or subtracting numbers in scientific notation :1. Determine the number by which to increase the smaller exponent by so it is equal to the larger exponent.2. Increase the smaller exponent by this number and move the decimal point of the number with the smaller exponent to the left the same number of places. (i.e. divide by the appropriate power of 10 .)3. Add or subtract the new coefficients.4. If the answer is not in scientific notation (i.e. if the coefficient is not between 1 and 10) convert it to scientific notation.Multiplication and Division in Scientific Notation Multiplication and DivisionQuantities with exponents can be multiplied and divided easily if they have the same base. Since all number in scientific notation have base 10 , we can always multiply them and divide them.To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents. In either case, the answer must be converted to scientific notation.Here are the steps to multiply two numbers in scientific notation:1. Multiply the coefficients--round to the number of significant figures in the coefficient with the smallest number of significant figures.2. Add the exponents.3. Convert the result to scientific notation.Here are the steps to divide two numbers in scientific notation:1. Divide the coefficients--round to the number of significant figures in the coefficient with the smallest number of significant figures.2. Subtract the exponents.3. Convert the result to scientific notation.
If two exponents have the same factor or base what happens to the exponents when the exponents are multipled?
The exponents are added.

what is 29's exponent and base
How do you divide exponents of the same base?
By subtracting the two exponents from each other.NOTE: can only be done if the base is the same, like 23/21=22Also, make sure to subtract in the correct order, taking the top exponent and subtracting the one beneath it.
What is a rule that works for multiplying powers of the same base in exponents?
To multiply powers with the same base, you add the exponents. For example, 10^2 x 10^3 = 10^5. Similarly, to divide powers with the same base, you subtract the exponents. For example, 10^3 / 10^5 = 10^(-2).
What does it mean to multiply two powers having the same base and add the exponents?
This is one of the laws of exponents, which states that xa * xb = x(a+b) The base is x, and the two powers (or exponents) are a and b.
When do add exponents?
when you multiply powers with the same base.
What are numbers expressed using exponents called?
Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base. For example, in 23 two is the base.
What is the relation of the exponent rule and the power rule?
The exponent "product rule" tells us that, when multiplying two powers that The Product Rule is that when you have the same base, you can add the exponents.The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56.
When multiplying number do you add the exponents?
If you are multiplying powers of the same base (like 24 times 211), yes, you add the exponents.
How do you simplify exponents or powers in algebra?
When multiplying exponents with the same base add them: x^3*x^2 = x^5 When dividing exponents with the same base subtract them: x^3/x^2 = x^1 or x
What property can you use to multiply the expressions with exponents?
The Addition Property of Exponents. To multiply powers with the same base, add the exponents. e.g. 34 x 37 = 311, x2x3 = x5, and (3x2yz3)(2x5y2z) = 6x7y3z4.
How do you divide powers with same base?
Subtract the powers. e.f. 2^(3 ) divide 2^(5) = 2^(3 - 5) = 2^(-2)
What is quotient of powers?
When you divide powers having the same base, subtract the numerator from the denomenator. Put the base in the part of the fraction where the original exponent was larger.
Why don't we change the exponents during like terms?
Exponents are higher in priority in terms of the order of operations, and do not combine in the same way as you would simple add/subtract/multiply/divide. So, if you have: 26 + 24 This is a polynomial in base 2 with different powers. It would be this in binary: 1010000 ...which would not be the same as 210: 1000000000 In order to be able to change exponents, you have to be multiplying factors using the same base, as in: 26 * 24 = 210 ...because the exponents are also indicating how many times you are multiplying each base by itself, and multiplication is the same as the basal function of the exponent (repeated multiplication).
