\(\left(0,125\right)^3.512=\left(\frac{1}{8}\right)^3.512=\frac{1}{512}.512=\frac{512}{512}=1\)
~ Rất vui vì giúp đc bn ~
\(\left(0,125\right)^3.512\)
\(=\left(0,125\right)^3.8^3\)
\(=\left(0,125.8\right)^3\)
\(=1^3\)
\(=1\)
(0.125)3 . 512
= \(\frac{1}{512}\). 512
= 1
\(=\left(0.125\right)^3.8^3\)
\(=\left(0.125.8\right)^3\)
\(=1^3=1\)
