Question

if p = 3n / m^3 then what is the effect of the value of p when n is multiplied by 4 and m is doubled?

Answer 1

To solve this probem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

$p=\frac{3n}{m^{3}}$

2. When $n$ is multiplied by $4$ and $m$ is doubled, and simplify the expression, you have:

p=$p= \frac{12n}{2 m^{3} } \\ p= \frac{6n}{ m^{3} }$

 The answer is: tex] 6n [/tex] is directly proportional to $p$ and $m^{3}$ is inversely proportional. Therefore, the result indicates that the value of $p$ will increase $6$ times.
