I believe the answer would be b^4.
Explanation:
Use Quotient Rule: x^a/x^b=x^a-b
b^10-6
Then Simplify 10-6 to 4
b^4
<u>Answer:</u>

Xy is the GCF of these expressions
Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
