i**j*i+*j
above line executed in following steps
1>i**j
3**3=9
2>i**j*i
9*3=27(9 from the previous step)
3>i**j*i+*j
27+*j=27+*j=27+3=30
above line executed in following steps
1>i**j
3**3=9
2>i**j*i
9*3=27(9 from the previous step)
3>i**j*i+*j
27+*j=27+*j=27+3=30

j=&i implies *j=i;
*j=3
i**j=3*3=9
i**j*i=9*3=27
i**j*i+*j=27+3=30
*j=3
i**j=3*3=9
i**j*i=9*3=27
i**j*i+*j=27+3=30

i**j*i+*j
Here the * symol before j is pointer value of j and * symbol before i and after i is for multiplication.
So the execution will be
i**J = 3*3 = 9
i**j*i = 9*3 = 27
i**j*i+*j = 27+3 = 30.
Here the * symol before j is pointer value of j and * symbol before i and after i is for multiplication.
So the execution will be
i**J = 3*3 = 9
i**j*i = 9*3 = 27
i**j*i+*j = 27+3 = 30.

i**j*i+*j
above line executed in following steps
i*(*j)*i+(*j)
now since i=*j=3
therefore
i**j*i+*j=i*(*j)*i+(*j)=3*(3)*3+(3)=30
above line executed in following steps
i*(*j)*i+(*j)
now since i=*j=3
therefore
i**j*i+*j=i*(*j)*i+(*j)=3*(3)*3+(3)=30

Munny and nihar gave correct explanation.

i**j*i+*j
It is executed in the following steps:
(i)*(*j)*(i)+(*j)
since *j=3 ie value at the address j, and as j stores address of i
so *j=3;
now,
(3)*(3)*(3)+(3)
=30

j=&i
& refer address of i right? How were you saying that j=3?

=i**j*i+*j {becoz *j=3)
=i**j*i+ 3
=i*3*i+ 3
=3*3*3+3
=30
=i**j*i+ 3
=i*3*i+ 3
=3*3*3+3
=30

i=3
j=&i---> *j=*(&i)---->*j=i---->*j=3
i**j*i+*j
=i*(*j)*i+(*j)
=3*3*3+3
=27+3
=30
j=&i---> *j=*(&i)---->*j=i---->*j=3
i**j*i+*j
=i*(*j)*i+(*j)
=3*3*3+3
=27+3
=30
