Answer:
[tex][11.5-(2.5*3)]^2=16[/tex]
Step-by-step explanation:
We want to evaluate [tex][11.5-(2.5*3)]^2[/tex]
Let us evaluate within the parenthesis first:
[tex][11.5-(2.5*3)]^2=[11.5-(7.5)]^2[/tex]
[tex]\implies [11.5-(2.5*3)]^2=[11.5-7.5]^2[/tex]
We again subtract within the bracket to obtain:
[tex][11.5-(2.5*3)]^2=[4]^2[/tex]
This finally gives us:
[tex][11.5-(2.5*3)]^2=16[/tex]
