Answer 1

Explicação passo a passo:

$4)\\ a)~~\sqrt{49} \\ \\ b)~~-5^3\\ \\ c)~~\sqrt{-25} \\ \\ d)~~\sqrt{9} =3\to oposto~~ -3\\ \\ e)~~|-2^5|$

-----------------------------------------------

$5)\\ A\\ (-4)^5=-1024\\ \\ B\\ -4^5=-1024\\ \\ C\\ (-3)^4-(-3)^4=\\ \\ +81-(+81)=\\ \\ 81-81=0\\ \\ D\\ (-3)^4+(-3)^4=\\ \\ +81+(+81)=\\ \\ 81+81=162$

$E\\ (-12)^2-(+10)^2=\\ \\ +144-(+100)=\\ \\ +144-100=+44\\ \\ F\\ (+3)^2-(-2)^5+(-4)^3=\\ \\ +9-(-32)+(-64)=\\ \\ +9+32-64=\\ \\ +41-64=-23$

$G\\ (-7)^3.(-2)^2+(-5)^3+(-6)^2:4=\\ \\ -343.~(+4)~+(-125)+(+36):4=\\ \\ -1372-125+9=\\ \\ -1497+9=-1488$

$H\\ (-1)^{10}+(-1)^{24}~.~(-1)^{35}~.~(-1)^{41}=\\ \\ (+1)+(+1)~.~(-1)~.~(-1)=\\ \\ +1+(+1)=\\ \\ +1+1=2$
