Question

\(\left(2x+^{2^5}\right).^{8^3=}^{8^5}\) so em viet hoi lo lung 1 ti

Answer 1

\(\left(2x+2^5\right).8^3=8^5\)

\(\left(2x+2^5\right)=8^5:8^3\)

\(\left(2x+2^5\right)=8^{5-3}\)

\(\left(2x+2^5\right)=8^2\)

\(2x+2^5=8^2\)

\(2x=8^2-2^5\)

\(2x=32\)

\(x=32:2\)

\(x=16\)

Answer 2

\(\left(2x+2^5\right).8^3=8^5\)

=>\(\left(2x+2\right).8^3=32768\)

=>\(\left(2x+2\right).512=32768\)

=>\(\left(2x+2\right)=32768:512=64\Rightarrow\left(2x+2\right)=64\Rightarrow2x=64-2=62\Rightarrow x=62:2=31\)

vậy x= 31

Answer 3

(2x+2^5).8^3=8^5
(2x+2^5)=8^5 : 8^3
(2x+2^5)=8^2
2 . x=8^2-2^5
2 . x=64-32
2 . x =32
     x=32:2
     x=16
