This is a power rule problem.
(d/dx)(x^{INT})
^[INT
]x\^[INT-1
]$
The power rule says that (d/dx)(x^n)=nx^{n-1}
.
Use the power rule with n=INT
.
It says (d/dx)(x^INT)=INTx^{INT-1}
.
Now you just have to compute that exponent: k=INT-1
.
Then, in the "Answer" box, you type in:
INT
x^k
but be sure to replace k
by the number that you computed.
