Subtracting numbers with same base but different power
Answers
Answer:
Even though the exponents are the same, these cannot be added or subtracted because their bases or exponents are different. Once we determine we do have the same bases and exponents, then all we need to do is add or subtract the coefficients.
Step-by-step explanation:
if you mean something of the form [math]x^a-x^b,[/math] then you cannot do the subtraction. (You can, however, factor out a power of x: [math]x^a-x^b=x^a \left( 1-x^{b-a} \right) = x^b \left( x^{a-b} - 1 \right).[/math])
If you mean using the formula [math]x^a \div x^b = x^{a-b},[/math] then you just subtract the numbers as indicated.
hope it helps u
Answer:
hey bro here is your answer
Step-by-step explanation:
When dividing terms with the same bases but different exponents, you will need to subtract all the pertinent exponents. becomes and stays the same because there is no other z term to combine with it.
