Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
If she is starting on day 1 with 0 followers and advances up 2 followers every day, by day "n" she would have 28 followers.
It lands on floor 5.
10-9+19-3-12

Answer:
The simplified form of the given expression is (2x-1).
Step-by-step explanation:
Consider the given expression is

According to the Inverse Properties of In

In the given expression the power of e is (2x-1).
Using the Inverse Properties of In, we get

Therefore, the simplified form of the given expression is (2x-1).
