Answer 1

Explicação passo-a-passo:

$a)~~6^2=6.6=36\\ \\ b)~~(-6)^2=(-6)(-6)=+36\\ \\ c)~~-6^2=-(6.6)=-(36)=-36\\ \\ d)~~(-2)^3=(-2)(-2)(-2)=-8\\ \\ e)~~-2^3=-(2.2.2)=-(8)=-8\\ \\ f)~~5^0=1\\ \\ g)~~(-8)^0=+1\\ \\ h)~~({3\over4})^4=({3\over4})({3\over4})({3\over4})({3\over4})={81\over256}\\ \\ i)~~(-{3\over4})^4=+{81\over256}\\ \\ j)~~(-{3\over4})^3=(-{3\over4})(-{3\over4})(-{3\over4})=-{27\over64}\\ \\ k)~~0^{23}=0\\ \\ l)~~1^{31}=1\\ \\ m)~~(-1)^{31}=-1\\ \\ n)~~(-1)^{12}=+1\\ \\ o)~~(-{3\over8})^2=(-{3\over8})(-{3\over8})=+{9\over64}$

$p)~~102^1=102$
