Step-by-step explanation:
The mathematical rules will be sued to evaluate the expression
In maths, first of all the round brackets are solved then the exponents and then other operations
Given expression is:
[tex]5-(1+2)^2[/tex]
First of all, we will solve the sum of 1 and 2 because it is in round brackets
So,
[tex]=5-(3)^2[/tex]
Solving the exponent, we get
[tex]= 5 - 9\\= -4[/tex]
Hence,
A. -4 is the correct answer
