8⁴ = 8x8x8x8 = 4096
8 with an exponent of four
20000 using the exponent of 4 = 11.89214fourth root of 20000 = 11.8921
120=8x3x5, but 8 is not a prime. We write 8 as 23 .Now the prime factorization is 23 x3x5. We stop because all the factors are primes raised to an exponent power..
You simply count the number of eights that are being multiplied together, and that is your exponent. In this case that would be: 8⁵
Exponent are easy, just count the amount of 7s or whatever # you are using and put that number to the top right
8 to the power of 2, like 8^2
