Answer
Find out the percent error in Annie's estimate .
To prove
Formula

As error = approx value - exact value
As given
Annie estimates that the height of a bookcase is 78.25 in.
The actual height is 75.50 in.
approx value = 78.25 in.
actual value = 75.50 in.
error = 78 .25 - 75 .50
= 2.75
put in the formula


Percentage error = 3.64 % (approx)
Therefore the Percentage error be 3.64 % (approx).

Lol i was working on this earlier. First get rid of the parenthesis by distributing the powers to the other powers.
27/4x(6)y(8)
the () are for powers
