Question

Answer 1

\(\dfrac{2^{10}.13+2^{10}.65}{2^8.10^4}=\dfrac{2^{10}.13.\left(1+5\right)}{2^8.2^4.5^4}=\dfrac{6.13}{2^2.5^4}=\dfrac{3.13}{2.5^4}=\dfrac{39}{1250}\)

Answer 2

\(\dfrac{2^{10}.13+2^{10}.65}{2^8.10^4}=\dfrac{2^{10}.\left(13+65\right)}{2^8.2^4.5^4}=\dfrac{2^{10}.78}{2^{12}.5^4}=\dfrac{2^{10}.2.39}{2^{12}.625}=\dfrac{2^{11}.39}{2^{12}.625}=\dfrac{39}{2.625}=\dfrac{39}{1250}\)
