Answer:
17
Step-by-step explanation:
8 + h^2
Let h = 3
8 + 3^2
We find the value of 3^2 first using PEMDAS
8 + 9
Then add
17
The result is 17
Solution: 17
Detailed explanation:
[tex]\circ[/tex] Stick in the value of h, which we're provided with (3)
[tex]--\mapsto\boldsymbol{8+(3)^2}[/tex] *
*Be careful here! Here it's very easy to make a mistake, if you aren't familiar with the Order of Operations. The Order of Operations is shown below [tex]\swarrow[/tex]
P=Parentheses
This operation tells us to perform the operations in the parentheses first.
E=Exponents
This one tells us to evaluate all exponents, if any are present.
M=Multiplication | D=Division
These two are completely interchangeable; you can perform Multiplication first and then division, or the other way around.
A=Addition | S=Subtraction
Like the two operations above, A and S are also completely interchangeable.

Using the information above, let's evaluate (find the value of) the expression [tex]8+h^2[/tex].
We stick in the value of h, 3
[tex]\pmb{8+3^2}[/tex] is what we obtain
Here we see that exponents are present (3^2) so we'll evaluate that first, as P.E.M.D.A.S. tells us to do.
[tex]\pmb{8+9}[/tex] (3^2=3*3)
And Now we just need to add the numbers
[tex]\boldsymbol{17}[/tex]
Voila! There's our answer!
