What operation should be done first to evaluate 10 + (66 - 6^2)?
(brainliest for best answer)

The exponential inside the parenthesis ( must be evaluated first

Solution:

Given that we have to find what operation must be done first to evaluate the following expression

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,

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

BODMAS tells us to do the exponential first. ( powers )

Therefore, exponential inside the parenthesis must be done first

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
