Question

\(2^{x+2}-2^x=96\)

Answer 1

2^x(2²-1)=96

2^x.4=96

2^x=24

=>x ko có giá trị

viết sai đề hả bạn à

Answer 2

\(2^{x+2}-2^x=96\Leftrightarrow2^x.4-2^x.1=96\)

\(\Leftrightarrow2^x\left(4-1\right)=96\Leftrightarrow2^x=32=2^5\Rightarrow x=5\)

Vậy ....

Answer 3

x=5 ik

Answer 4

2^x+2-2^x=96

=>2^x(2^2-1)=96

=>2^x.3=96

=>2^x=32

=>x=5

Answer 5

2^x.(4-1)=96

2^x.3 = 96

2^x=32

2^x=2^5

x=5 

vậy x=5

Answer 6

2^x+2 - 2^x = 96

2^x. 2² - 2^x = 96

2^x. ( 2² - 1)=96

2^x. 3 =96 

2^x     = 96 : 3

2^x      =  32

2^x   =   2⁵

=> x = 5
