How do you simplify #11\times 3- 5^ { 2}#?

Answer 1

The Simplified Answer Is: #8#.

In this example, we always will start with simplifying the exponent. Since the exponent given is #-5^2#, we must simply that first. See below:

#-5^2=-25#

Since a negative #(-)# number without parenthesis squared is a negative number, we are given #-25#.

Now we can multiply #11# and #3# together. See below:

#11*3=33#

Therefore, we now have an equation such as:

#33-25=?#

Simply the expression to obtain the answer:

#33-25=8#

Following PEMDAS (or whatever way works for you) is really important when doing these types of equations/expressions.
