Question

(4^13 - 4^12) / (4^11)

Answer 1

split into 2 parts, it would becomes
4^13/4^11 - 4^12/4^11
now use the property exponent :
a^m/a^n = a^(m-n)
continue it ...

Answer 2

So it should be 4^2 - 4^1
=16 - 4
=12

Thank you!

Answer 3

another way is factor out 4^12 from the parens

(4^13 - 4^12) / (4^11)
(4 - 1) 4^12/4^11
3 * 4
12

Answer 4

Thank you, both!
