Current is scaler because it is produced due to drift movement of charge and current density is vector because current per unit area which means in particular wire current flows,and that wire have particulare surface area,so this surface area have its normal vector which is perpendicular to that surface area, so j=I/A(vector) ,any scaler quantity divided by vector is vector quantity. So current density is vector quantity read less

Actually current density is current per unit area. The area taken over here is the area vector which has its own magnitude and direction(directed normal to the projected area)

current is the dot product between area (a vector) and current density (vector) hence the result is scalar.

When power of any number have 0 then it gives a value equal to 1. Why ?
If we divide 2^m by 2^n we get 2^m-n. Now 2^1/2^1=2^0 3^1/3^1=3^0 , 4^1/4^1=4^0. If any number is divided by itself we get 1. So 2^0=1 , 3^0=1 , 4^0=1
