Math.pow(2,3), here 2 is base and 3 is power. You don't need to import any package. Did you mean without using any library function? Hint: To calculate 2^3 using loop, you need to multiply 2 with itself 3 times. 2^3 = 2*2*2

You can't initialize using ^ operator. It has different meaning. There's no such operator for power. You'll have to use library function Math.pow()

Are you talking about finding the power without using any functions ?

you have to use math.pow it's return type is double .so u have to do type casting INT k=Integer.parseInt(math.pow(i,j)) or INT k= (int)math.pow(i,j)
