Answer 1

Hey there! I'm happy to help!

When evaluating the value of an expression, we need to follow the order of operations which is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction).

First, we will evaluate the exponent. 3² is 3×3 which is 9.

$\frac{9+2*8}{16-11}$

Now we have to do multiplication. Since the multiplication sign is between the 2 and the 8, that is what we multiply.

$\frac{9+16}{16-11}$

Then we will do our addition and subtraction.

$\frac{25}{5}$

Since all fractions are just division problems, we can do 25÷5.

25÷5=5

So, the value of this expression is 5.

Have a wonderful day and keep on learning! :D

Answer 2

Step-by-step explanation:

$\frac{3 ^{2} + 2.8 }{16 - 11} \\ \frac{9 + 2.8}{16 - 11} \\ \frac{11.8}{5} \\ 2.3$
