Question

oblicz: 2^3*4^5kreskaulamkowa(8^2)^5=

Answer 1

2^3 * 4^5     2^3 * (2^2)^5       2^3 * 2^10

----------- = ------------------- = ------------ = 2^13 : 2^30 = 2^(-17) = (1/2)^17

(8^2)^5        (2^3)^10                 2^30

Answer 2

....= (2^3 * (2^2)^5 /( (2^3)^2)^5 =

=(2^3 * 2^10) / 2^30 =

= 2^13/2^30=

=2^(13-30)=

=2^-17
