Question

HELPPP!!
Solve this equation algebraically -
2^x+2^-x=5

Answer 1

2^x + 1/2^x = 5
(2^x)^2 + 1 = 5 (2^x)
??

Answer 2

(2^x)= ???

Answer 3

\[2^x + 2^{-x} = 5 = 2^x + \frac{1}{2^x}\]
\[(5) 2^x = 2^x 2^x + 1\]

Answer 4

\[\log 5 + x(\log 2) = 2x(\log 2) + \log(1) = 2x(\log 2)\]

Answer 5

thank youuu
