If the number can be written as 2*3*5 it cannot be prime!
Index form is where a number is expressed as the exponents of its prime factors. At the moment, you have it as its prime factors. We have two 3s, so that can be given as 32 and we have four 4s, so that can be given as 44. Thus 3x3x4x4x4x4 in index form is 32x44
