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]
