Answer :
The exponential inside the parenthesis ( [tex](6^2)[/tex] must be evaluated first
Solution:
Given that we have to find what operation must be done first to evaluate the following expression
[tex]10 + (66 - 6^2)[/tex]
We have to use BODMAS rule , to determine the sequence of operations that must be done first
Bodmas stands for "brackets, orders, division, multiplication, addition, subtraction"
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.
Therefore, in the given expression,
[tex]10 + (66 - 6^2)[/tex]
As per BODMAS rule, we have to evaluate the terms inside the bracket first
Within the parenthesis, we have a Subtraction and an Exponential.
i.e [tex](66 - 6^2)[/tex]
BODMAS tells us to do the exponential first. ( powers )
Therefore, exponential inside the parenthesis must be done first
