Solve the equation after making an appropriate substitution. x^6-98x^3=3375

Rearrange  to give



Let  be a variable 'p' and so we can write  as 

Rewrite the equation in terms of 'p'



where 

using the quadratic formula  and subsitute the value of 





There are two value of p; 125 and -27 

Now we find the value of x

Earlier we substitute  for  and  for 

When , 
When 

So the final answer is the two values of x; 

x = 5 OR x = -3

Iwould say this is false, because the mean and median are similar, though the mode is way different. but it might be true depending how you like at it. sorry if i'm being confusing : )

The integer in this is 89.5 so the third number would be 359.5
