[tex]7^3\cdot7^6:(7^4)^2=7^3\cdot7^6:7^8=7^{3+6-8}=7^1=7\\\\\\5^7\cdot5^3:(5^4)^2=5^7\cdot5^3:5^8=5^{7+3-8}=5^2=25\\\\\\\dfrac{3,6\cdot10^5}{3\cdot10^6}=\dfrac{3,6}{3}\cdot\dfrac{10^5}{10^6}=1,2\cdot10^{5-6}=1,2\cdot10^{-1}=1,2\cdot\frac{1}{10}=1,2\cdot0,1=0,12[/tex]
[tex]\dfrac{4,8\cdot10^4}{2\cdot10^5}=\dfrac{4,8}{2}\cdot\dfrac{10^4}{10^5}=2,4\cdot10^{4-5}=2,4\cdot10^{-1}=2,4\cdot\frac{1}{10}=2,4\cdot0,1=0,24[/tex]
