Not sure about what exactly is being asked, but if I'm interpreting correctly:
If you are to divide a^x by a^y (that is, a raised to the x power and a raised to the y power, respectively)
(a^x) / (a^y) = a^(x-y)
If the numbers are both of the same base, from the exponent in the numerator subtract the exponent in the base.
Ex)
(3^10) / (3^8) = 3^(10-8) = 3^2 = 9
To verify, check that 59049 / 6561 = 9.
Remember: negative exponents are positive exponents on the other side of the division sign. To return to the example above, assume we switched the numerator and denominator.
Ex) (3^8)/(3^10) = 3^(8-10) = 3^(-2) = 1/(3^2)
When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.
Yes. When you divide one variable with an exponent from another, you subtract the exponents
You subtract the exponent of the denominator from that of the numerator.
When dividing numbers with exponents, subtract the bottom exponent from the top exponent.
kahit ano sagot
It wasn't necessary to 'create' any rules. They follow logically from the definition of exponents.
When dividing numbers (or variables) subtract the exponents. Remember, an exponent indicates a kind of multiplication, it is the number of times that a number is multiplied by itself. If you are dividing by that same number, then clearly you are multiplying it by itself a fewer number of times. Division is the inverse function of multiplication.
Subtract them.
i guess u subtract the exponents
None. You substract. 5^8/5^5 = 5^(8-5)=5^3
You subtract the exponent of the divisor from that of the dividend.
The quotient rule of exponents in Algebra states that dividing expressions with the same base you subtract the exponents. However, the base cannot be equal to zero.The above statement follows this rule in Algebra:xm/xn = xm-n;x cannot equal 0Here's an example:x15/x5 = x15-5 = x10
