Question

4 si 5!!! Va roooooooggggg!!!!

Answer 1

4)

a) = 2^(9+11) = 2^20

b) = 5^(3+12) = 5^15

c) = 7^(19-11) = 7^8

d) = 3^(23-12) = 3^11

e) = 2^(9x11) = 2^99

5)

a) = 2^3 x 2^6 = 2^9

b) = 3^15 : 3^2 = 3^13

c) = 3^12 x 3^3 = 3^15

e) = 5^15 : 5^2 = 5^13

f) = 2^20 : (2^2)^8 = 2^20 : 2^16 = 2^4
