Simplify the expression above. Which of the following is correct?

Let's simplify the expression step by step:

Step 1: Inside the square brackets, perform the operation within parentheses first:

([4(3+6?5)]=[4(3+30)] ) 

Step 2: Continue simplifying inside the square brackets:

([4(3+30)]=[4ast33])

Step 3: Calculate the value inside the square brackets:

([4ast33]=132)

Step 4: Now, deal with the denominator:

((20÷5)=4)

Step 5: Finally, divide the result from step 3 by the result from step 4:

(132/4=33)

So, the simplified expression is 33.

We follow the order of operations to solve the given expression.

First, we start with the numerator and solve

[2(8+2*6)]

We start with multiplication in inner brackets, 2*6=12. The expression becomes

[2(8+12)]

Then, we conduct the addition of 8+12=20. Then, the expression yields

[2(20)] = 2*20 = 40

Now, we solve for denominator, which is 16/2=8.

Thus, the expression is reduced into

\(\frac{2(8 + 2 \times 6)}{\left(\frac{16}{2}\right)} = \frac{40}{8} = 5\)

The expression reduces into 5.

We are asked to find a fraction of pizza other three friends got.

A whole pizza represents 1, and one friend eats 1/3 of 1=1/3*1=1/3

Now, the remaining pizza is 1-1/3=3/3-1/3=2/3

The three friends share 2/3 of pizza equally. So, each friend gets

Therefore, each of the three friends get 2/9 of the pizza.

we use the calculator to determine the positive square root of 33, which is then multiplied by 15.

Using the calculator,

Multiplying the square root above with 15 becomes

The approximate value is 86.2.

Let's break down the problem:

1. One friend eats three-quarters of the pizza.
2. This means there is one-quarter of the pizza remaining.
3. The other two friends equally divide this remaining quarter among themselves.

Since two friends are dividing the remaining quarter equally, each friend receives 1/2of the remaining quarter.

So, each of the other three friends receives 1/2*1/4 of the whole pizza.

1/2*1/4=1/8

So, each of the other three friends receives 1/8of the pizza.

Therefore, the correct answer is not provided among the options given. The closest fraction among the options is 1/6.
