For this case we must find the quotient of the following expression:

We have to:

By definition of power properties we have:

So so:

Answer:
Option A
4+{[3-2).2-5].4
1st proceder a la multiplicación ==> 4+{(6-4) -5}4
2nd Quitar los paréntesis ==> 4+{2-5}4==> 4+{-3}4
3rd multiplicación: 4+{-12}
4th = - 8
Pemdas
parenthasees
exponenes (includes square root)
mult or division from left to right
add or subtract from left to right
so parenthasees are good
multiply first and vidied(-6 times 4)+(-7 times 3)=-24-21
then add or subtract
-24-21=-45
Answer:
Evaluating the piecewise function when X =3, we get f(3) = 7
Step-by-step explanation:
Given the following piecewise function
f(x)= { 2x+1; where x > 0
-3 when x ≤ 0
Evaluate the function when X = 3
We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0
We can't use -3, because x ≤ 0, and 3 is not less than 0.
Now, evaluating the function:

So, Evaluating the piecewise function when X =3, we get f(3) = 7
