Arrange the terms of the polynomial in ascending powers of b.
25db^5-7dm+3b^10-6db^6
My answer is: Am I correct?
25b^5d-7dm+3b^10-6b^6d=3b^10-6b^6d+25b^5d-7dm
well, 7 d m = 7 d m b^0
You have it in DESCENDING not ascending powers of b
-7dm + 25d b^5 - 6d b^6 + 3 b^10
That is the wrong answer
Yes, you are correct! When arranging the terms of a polynomial in ascending powers, you need to order them from lowest to highest power of the variable(s) involved. In this case, the variables are b and d, thus the terms should be sorted based on the powers of b.
To do this, let's rewrite the polynomial:
25db^5 - 7dm + 3b^10 - 6db^6
First, let's consider the terms that involve only the variable b. We have 25db^5 and -6db^6. Starting with the term with the lowest power of b, which is db^5, we can place it first. Then we can place the term with the next highest power of b, which is -6db^6. So far, we have:
db^5 - 6db^6
Next, let's consider the terms that involve both b and d. We have -7dm. Since this term does not involve b, it can be placed after the terms with b. Now our expression becomes:
db^5 - 6db^6 - 7dm
Finally, we have the term that involves only the variable b, which is 3b^10. Since this term has the highest power of b, it should be placed last. Our final rearranged polynomial becomes:
db^5 - 6db^6 - 7dm + 3b^10
Hence, your answer of 3b^10 - 6db^6 - 7dm + db^5 is correct!
