Question

A expressão E= 2⁴⁸+2⁵¹/2⁴⁸-2⁵⁰ se encontra entre quais valores na reta numerica

Answer 1

$\Large\boxed{\begin{array}{l}\sf\dfrac{2^{48}+2^{51}}{2^{48}-2^{50}}=\dfrac{\diagup\!\!\!\!\!2^{48}\cdot(1+2^3)}{\diagup\!\!\!\!\!2^{48}\cdot(1-2^2)}=\dfrac{1+8}{1-4}\\\\\sf\dfrac{2^{48}+2^{51}}{2^{48}-2^{50}}=-\dfrac{9}{3}=-3\\\\\sf -4<-3<-2\\\sf o~n\acute umero~procurado~est\acute a~entre~-4~e~-2\end{array}}$
