I'm not sure what you mean by 'index notation', but 70 factors into 2*5*7. 2*2*5*5 = 100, etc. You do a couple of them ☺

have you seen a factorization tree? Basically, you divide the number by two or three, or any other prime number until you only have prime numbers left. Then it's prime factorization is the product of all the prime numbers.
a. 70 is 2x35, 35 is 5x7. Both 5 and 7 are prime so it's prime factorization is 2x5x7
b. 96 is 2x48, 48 is 2x24, 24 is 2x12, 12 is 2x6, 6 is 2x3. 3 is prime. So 96's prime factorization is 2x2x2x2x2x3.
You do the others.

the first prime numbers you have to learn by heart they are:
2,3,5,7,11,13,17,19,23,19,31
now you have the material to solve your problem
a)
70= 35*2=7*5*2
=================
b)96=48*2=24*2*2=
4*6*2*2*2=2*2*3*2*2*2=
2^5*3
==============================
c) 100=10*10=2*5*2*5= 2^2*5^2
============================
d)150=3*50=3*2*25=3*2*5*5=3*2*5^2
======================
e) 256= 128*2=64*2*2=
8*8*2*2=2*4*2*4*2*2=
2*2*2*2*2*2*2*2=8^2

a. 70 = 2 * 5 * 7
b. 96 = 2 * 2 * 2 * 2 * 2 * 3, or 2^5 * 3
c. 100 = 2 * 2 * 5 * 5, or 2^2 * 5^2
d. 150 = 2 * 3 * 5 * 5, or 2 * 3 * 5^2
e. 256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 2^8
