A students finds a resistance in a transistor radio. When the resistance is connected to a battery of 1.5 volts, the current is 0.0025 amperes. When the resistance is connected to four batteries with a voltage of 1.5 volts, the current measures to be 0.1 amperes. When the resistance is connected to a battery of 9V, the current measures to be 0.15 amperes. Are these resistances an ohmic resistance? Explain.

R = V/i
1.5/.0025 = 600 Ohms
step 2 is meaningless because you do not say if the batteries are in series or parallel.
9/0.14 = 60 Ohms
So no, resistance is not constant
However I bet you have a typo.
