When dividing variables that ave the same base, keep the base and subtract the powers.y^9/y^3 = y^(9 - 3) = y^6
The answer is y^6
Answer:
common difference=5
number of term(n)=20
Step-by-step explanation:
a=4,
but T_{4} =19= a+3d
a+3d=19
4+3d=19
3d=19-4
3d=15
d=15/3
d=5
=a+(n-1)d
99=a+(n-1)d
99=4+(n-1)*5
99=4+5n-5
99=5n-1
5n-1=99
5n=99+1
5n=100
n=100/5
n=20
x− ((x−1)/3) − ((2x−5)/5) + ((x+8)/6) =7
x = 10

<span>A1 is the 1st term r is the difference, they can say "r" or "d" for the difference 1st a1 is the first term = -3 2nd "r" is the difference between each consecutive terms (coming after each other) = 1.5 the rule to get any term of the sequence as we add 1.5 each time is --> a1+(n-1)*d a1 --> 1st term , n --> order of the term u want whether 2nd, 3rd , 25th d --> difference so to get the 2nd--> -3+(2-1)*1.5= -1.5 to get the 3rd --> -3 +(3-1)*1.5 = 0 and so on</span>
