Question

4^x+2 -3.4^x=832

Nhanh hộ mình nha

Thank

Answer 1

4^x  . 4^2 -3 . 4^x=832

4^x.(16-3)=832

4^x=64

x=3

Answer 2

4^x+2 -3.4^x=832

=> 4^x . 4² -3 . 4^x = 832

=> 4^x (4² - 3) = 832

=> 4^x             = 64 = 4³

=> x = 3

 

Answer 3

4^x.4²-3.4^x=832

4^x.(4²-3)=832

4^x.(16-3)=832

4^x.13=832

4^x=832:13

4^x=64

4^x=4³

x=3

Answer 4

\(4^{x+2}-3.4^x=832\)

\(\left(4-3.4\right)^{x+2}=832\)

\(-8^{x+2}=832\)

\(^{x+2}=832:\left(-8\right)\)

\(^{x+2}=-104\)

\(^x=-104-2\)

\(^x=-106\)
