Answer:
The code is as below. The solution is given in python and can be converted to other programming language.
Explanation:
As the language is not identified, it is assumed that the requirement of the language is python
As the complete question is missing, here the link to complete question is given in the comments above.
From the complete question, it is given that the approximated solution is for x86 instruction. thus as the x86 instructions are for integers only thus the complete code is as follows: Here the code is given as
#Defining the function
def relerror(x):
x=float(x);
y=int(x)
f_h=y**(0.72);
f=x**(0.72);
absol=abs(f_h-f);
rel=absol/f;
relp=(absol/f)*100;
print('The relative error for',x,' as value of x when approximated as x86 routine is ',round(relp,2),'%')
#Main program calling given function
x=input('Please enter a value in float')
relerror(x)
