\(2^x+2^{x+4}=544\)
=>\(2^x+2^x\cdot2^4=544\)
=>\(2^x\left(1+2^4\right)=544\)
=>\(2^x\cdot17=544\)
=>\(2^x=\dfrac{544}{17}=32\)
=>\(2^x=2^5\)
=>x=5
\(2^x+2^{x+4}=544\)
\(\Rightarrow2^x+2^x\cdot2^4=544\)
\(\Rightarrow2^x\left(1+2^4\right)=544\)
\(\Rightarrow2^x\cdot17=544\)
\(\Rightarrow2^x=32\)
mà \(2^5=32\)
Suy ra: \(x=5\)
Vậy \(x=5\) là giá trị cần tìm.
2x + 2x + 4 = 544
=> 2x . 1 + 2x . 24 = 544
=> 2x . (1 + 16) = 544
=> 2x . 17 = 544
=> 2x = 32
=> 2x = 25
=> x = 5
Vậy x = 5.

\(2^x+2^{x+4}=544\)
\(2^x.1+2^x.2^4=544\Rightarrow2^x.\left(1+2^4\right)=544\)
\(2^x.17=544\Rightarrow2^x=544:17=32\)
\(\Rightarrow2^x=2^5\Rightarrow x=5\)
Vậy \(x=5\)
\(1,\sqrt{3}x-3=\sqrt{27}\)
\(\Leftrightarrow\sqrt{3}x-3=3\sqrt{3}\)
\(\Leftrightarrow\sqrt{3}\left(x-\sqrt{3}\right)=3\sqrt{3}\)
\(\Leftrightarrow x-\sqrt{3}=3\)
\(\Leftrightarrow x=3+\sqrt{3}\)
\(2,\sqrt{2}x-\sqrt{28}=\sqrt{32}\)
\(\Leftrightarrow\sqrt{2}x-2\sqrt{7}=4\sqrt{2}\)
\(\Leftrightarrow\sqrt{2}x=4\sqrt{2}+2\sqrt{7}\)
\(\Leftrightarrow x=\dfrac{\sqrt{2^2}\left(2\sqrt{2}+\sqrt{7}\right)}{\sqrt{2}}\)
\(\Leftrightarrow x=\sqrt{2}\left(2\sqrt{2}+\sqrt{7}\right)\)
\(\Leftrightarrow x=4+\sqrt{14}\)
\(3,\sqrt{6}x-2\sqrt{6}=\sqrt{54}\)
\(\Leftrightarrow\sqrt{6}\left(x-2\right)=3\sqrt{6}\)
\(\Leftrightarrow x-2=3\)
\(\Leftrightarrow x=5\)
\(4,\sqrt{3}x-\sqrt{2}x=\sqrt{3}+\sqrt{2}\)
\(\Leftrightarrow\left(\sqrt{3}-\sqrt{2}\right)x=\sqrt{3}+\sqrt{2}\)
\(\Leftrightarrow x=\dfrac{\sqrt{3}+\sqrt{2}}{\sqrt{3}-\sqrt{2}}\)
2x + 2x + 4 = 544
\(\Rightarrow\) 2x + 2x . 24 = 544
\(\Rightarrow\)2x . ( 1 + 24 ) = 544
\(\Rightarrow\)2x = 544 ÷ 17
\(\Rightarrow\)2x = 32 = 25
\(\Rightarrow\)x = 5
Vậy : x = 5
2x+2x+4=544
2x+2x.24=544
2x.(1+16)=544
2x.17 =544
2x =544:17
2x =32=25
=>x=5
Vậy x=5
hok tốt
2x + 2x+4 = 544
<=> 2x + 2x.24 = 544
<=> 2x( 1 + 24 ) = 544
<=> 2x.( 1 + 16 ) = 544
<=> 2x.17 = 544
<=> 2x = 32
<=> 2x = 25
<=> x = 5
