Explain how to write 50000 using exponents
Yakvenalex [24]
I think i need a bit more information but assuming if this is what you are looking for:

to write 50,000 in exponent form look for its multiples other than 1 and itself and then go from there.

This is what i general do, i pick a divisible number and keep dividing till i get to one.


50,000/2 = 25,000
25,000/5 = 5,000
5,000/10 = 500
500/10 = 50
50/10 = 5
5/5 = 1
so i divided by 2, 5,10, 10, 10, and 5 (three 10s, two 5s and one 2)

then i look if these numbers can be written in smaller divisible numbers (i.e. 10 is 2 and 5)

so 2, 5, (2,5), (2,5) ,(2,5), and 5 as you can see that cannot be divided into smaller numbers so we have thus five 5s and four 2s

therefore 50,000 = 5^5 x 2^4

hope this helps :P

(P.S. it is the best way i can explain online without a whole course on this)

15/15 - 11/15 = 4/15

Part C= 4/15
