8-m/n+p^3= 8-8/2+7^2       sub in the numbers for the variables
(8-8)/2+7^2                         Exponents
(8-8)/2+49                           add the denominators together
(8-8)/60                               subtract 8-8
0/60                                     is the answer (which doesn't seem right to me)

Answer: 53.

Step-by-step explanation:

The given expression : [tex]8-\dfrac{m}{n}+p^2[/tex]

To find : The value of the above expression for the values m=8, n=2 and p=7.

For that , we just substitute the gives values m=8, n=2 and p=7 in the above expression by using Substitution property  , we get

[tex]8-\dfrac{8}{2}+(7)^2[/tex]  

Simplify,

[tex]=8-4+49[/tex]  

[tex]=4+49=53[/tex]    

Hence, the correct value of the given expression when m=8 n=2 p=7 is 53.
