Answer:

B.) 13

C.) 0.6

Step-by-step explanation:

The order of operations to evaluate these expressions is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

So, for B.)

9^\frac{1}{2}+\sqrt{25}-8\div2+3^2

This can be rewritten as
9^\frac{1}{2}+25^\frac{1}{2}-8\div2+3^2

Since there are no parentheses, evaluate the exponents first:

3+5-8\div2+9

Next, there are no multiplication steps, but there is one division:

3+5-4+9

To finish, evaluate from left to right:

3+5-4+9
8-4+9
4+9
13

Follow the same pattern for C.)

(\frac{1}{2})(\frac{3}{5})(2^3-6)

This expression can be rewritten as

(1\div2)(3\div5)(2^3-6)

First, evaluate the expressions in the individual parentheses, keeping in mind the expression (2^3-6) must be evaluated following the same pattern (evaluate the exponent before subtracting six):

(.5)(.6)(8-6)
(.5)(.6)(2)

To finish, evaluate from left to right:

(.3)(2)
.6

Hope that helps!
