The error was in second step.
3√(y^3)^4 = y^4
(Cube root cancels cube and not power 4)
The answer should be:
xy^4/4

If the dinner altogether costs £64, and there is a 20% tip, that brings the total amount paid to £76.80, and if four people are paying £19 towards the total, then there would not be enough for them to pay for both the meal and the tip, as 19x4 is 76, and the total is £76.80, meaning you need another 80 Pence.
Answer: No, as there is 80 pence off the total amount with all of there money added together which they would need to pay for the meal and the tip.

Step-by-step explanation:
Hello,
"Find the sum of the following infinite geometric series"
infinite
We will have to find the limit of something when n tends to
geometric series
This is a good clue, meaning that each term of the series follows a geometric sequence. Let's check that.
The sum is something like
First of all, we need to find an expression for
First term is
Second term is
Then
and...
Ok we are good, we can express any term for k integer
So, for n positive integer
And the limit of that expression when n tends to is
as
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
