Answer:

\text{C. }1

Step-by-step explanation:

In the question, we're given that the notation \#\#(a,b,c) produces a number a less than the product of b and c raised to the a power. Let the number produced be n. As a mathematical equation, we can write this production as n=(bc)^a-a

For \#\#(2, 5, x), we can assign:

  • a\implies 2
  • b\implies 5
  • c\implies x

Substituting these values into n=(bc)^a-a, we get:

23=(5x)^2-2

Add 2 to both sides:

25=(5x)^2

Take the square root of both sides:

5=|5x|

For y=|z|, there are two cases:

\begin{cases}y=z,\\y=-z\end{cases}

Therefore, we have:

\begin{cases}5=5x, x=\boxed{1}\\5=-(5x), 5=-5x, x=\boxed{-1}}\end{cases}

The only answer choice applicable is \boxed{\text{C. }1}.

Answer:

 

Simplify  {4}^{2}42  to  1616.

-16+2\times -4\times -5-2\times {2}^{3}−16+2×−4×−5−2×23

 

Simplify  2\times -42×−4  to  -8−8.

-16-8\times -5-2\times {2}^{3}−16−8×−5−2×23

 

Simplify  8\times -58×−5  to  -40−40.

-16-(-40)-2\times {2}^{3}−16−(−40)−2×23

 

Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}xaxb=xa+b.

-16-(-40)-{2}^{4}−16−(−40)−24

 

Simplify  {2}^{4}24  to  1616.

-16-(-40)-16−16−(−40)−16

 

Remove parentheses.

-16+40-16−16+40−16

 

Simplify  -16+40−16+40  to  2424.

24-1624−16

 

Simplify.
