b)360:10.6=36.6=216

c)3^2.8:12.13:39=9 8:12.13:39=72:12.13:39=78:39=2

d)5.12.17:255=60.17:255=1020

e)12.11:44.16:24=3.16:24=48:24=2

456:24.5^2:19.20=475:19.20=25.20=500

3.

10^60:(2.5)^58= 10^60 : 10^58=10^60-58=10^2=100

(7^14.5)^2:7^26=7^28.5^2:7^26=49.25=

1225

(7

^6)^8:49^24=7^48:(7^2)^24=7^48:7^48=7^0=1

(3^4)^9:(9^6)^3=3^36:9^18=3^36:3^36=1

(11^2011.4^1005):[(22^2)^5]^201=(11^2011.2^2010):22^2010=(11^2011.2^2010):(11^2010.2^2010)=11

2^23:2^21:2+3^32:3^31.3=2+3^2=2+9=11
