Question

Divide:

50a^11/ 4a^16

Answer 1

are you familiar with the rules to do with indexes?

Answer 2

e.g.:\[a^n/a^m=a^{n-m}\]

Answer 3

\[{x^a \over x^b} = x^{a-b}\]

Answer 4

if not, then you might find this problem a bit more difficult

Answer 5

you can think of it as:\[\frac{50a^{11}}{4a^{16}}=\frac{50*a*a*a...*a}{4*a*a*a...*a}\]
where the numerator has 11 multiples of "a" and the denominator has 16 multiples of "a"

Answer 6

so all you need to do is to cancel the common factors in this fraction.
can you do that?

Answer 7

So 50 * a^11/4a^16 = (50/4) * a^11/a^16=
= 12,5 * a-5 or 12,5/a^5
If you prefer, 50/4*a^5 to

Answer 8

alright got it
