Oh honey, let me break it down for you. 160 can be expressed as 2^5 * 5^1. In index form, that would be written as 2^5 * 5. So there you have it, 160 expressed as a product of prime numbers in index form. Hope that clears things up for ya!
2^2 x 3 x 5 = 60
80 as a product of prime numbers can be expressed as: 2x2x2x2x5
As a product of its prime factors: 2*61 = 122.
Neither 90 nor 500 are prime numbers.
420=2x2x3x5x7
23 x 33 = 216
2^2 x 3 x 5 = 60
840 = 23 x 3 x 5 x 7
80 as a product of prime numbers can be expressed as: 2x2x2x2x5
As a product of its prime factors: 2*61 = 122.
Neither 90 nor 500 are prime numbers.
It is: 24*112 = 1936
420=2x2x3x5x7
2x2x2x3 = 24
As a product of its prime factors: 5^3 times 13 = 1625
360= 23 times 45
As a product of its prime factors: 2*2*3*7 = 84
