PEMDAS,

P = parenthesis
E = exponent
M = multiplication
A = addition
S = subtraction

4 - 16/4 + 4²

P = not available
E = 4² = 16
M = not available
D = -16/4 = - 4
A = +4

= 16 - 4 + 4 = 16

4 - 16 ÷ 4 + 4²

If you remember PEMDAS, then you know that the first thing you'll do here is the exponent.

4 - 16 ÷ 4 + 16

Next is division.
4 - 4 + 16

Now work out the rest from left to right.
0 + 16
16

The answer is 16.

kherson [118]

Answer:

U = -3

Step-by-step explanation:

U/-1 +-4=-1

Add 4 to each side

U/-1 +-4+4=-1+4

U / -1 = 3

Multiply each side by -1

U / -1 * -1 = 3* -1

U = -3

Choose the correct simplification of the expression ( 4x/y)^2.

erik [133]

$\large\displaystyle\text{$\begin{gathered}\sf \left(\frac{4x}{y}\right)^{2} \end{gathered}$}$

To raise 4x/y to a power, raise the numerator and denominator to the power, and then divide.

$\large\displaystyle\text{$\begin{gathered}\sf \frac{(4x)^{2} }{y^{2} } \end{gathered}$}$

Expand (4x)².

$\large\displaystyle\text{$\begin{gathered}\sf \frac{4^{2} x^{2} }{y^{2} } \end{gathered}$}$

Calculates 4 to the power of 2 and gets 16.

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf \frac{16x^{2} }{y^{2} } \end{gathered}$} }$

2. An expression is shown.

laiz [17]

Adding parentheses in the component $9\div 3$ of the expression may bring an output of 48.

<h3>Procedure - Application of hierarchy rules in a arithmetic expression</h3>

In this question we should make use of hierarchy rules represented by the use of parentheses. The parentheses oblige to make operations inside it before making it in the rest of the formula.

Now we decide to add parenthesis in the component $9\div 3$ such that the result of the entire expression is 48. We proceed to present the proof:

$2 \times 8 \times (9\div 3)$

$2\times 8 \times 3$

$2\times 24$

$48$

Adding parentheses in the component $9\div 3$ of the expression may bring an output of 48. $\blacksquare$

<h3>Remarks</h3>

The statement presents mistakes and is poorly formatted. Correct form is shown below:

An expression is shown: $2\times 8 \times 9 \div 3$

Using the same expression, add parenthesis so that the value of the expression is 48.
