That's D. n² ÷ 5 because it says the division of n squared and 5.
Answer: 1/x + 7
Step-by-step explanation: you plug the function g(x) into the function f(x) .. substitue g(x) for the x in f(x)
G(x) = 1/x , so you plug that in the x of f(x) and get 1/x + 7
"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409.
The greatest possible value of that fraction is. (239)/(409 squared) .
The main reason behind this is using properties of logarithm .

when solving
There you use multiplication property and make addition to multiplication then you get extraneous solution because in plenty of cases they occur

But
Same happens in case of logarithm
