1) b^13*b*b^21*b^20=b^(13+1+21+20)=b^55
2) 16^4*4^10*64^5=
=(2^4)^4*(2^2)^10*(2^6)^5=
=2^16*2^20*2^30=
=2^66
3) c^58*c^39*c^9=c^(58+39+9)=c^106
4) 125^42:25^63=
=(5^3)^42:(5^2)^63=
=5^126:5^126=
=1
5) [(2^3)^37*(3^4)^25]:[(2^4)^27*(3^3)^33]=
=(2^111*3^100):(2^108*3^99)=
=2^3*3=
=8*3=
=24
6) 2^(1+2+3+...+45)=2^(45*46/2)=2^(45*23)=2^1035
7) 1
