Let u=2^x and solve for u. u=1 (double) gives x=0 and u=(3+or-sqrt5)/2 gives x=log((3+or-sqrt5)/log2)-1.
X=0, (log3+√5/ log 2)-1, (log3-√5/ log 2)-1
Let t=2^x. Then, [t^4+8t^2+1]/[[t^3+t] = 5 > t^2[t^2+1/t^2+8]/[t^3+t] = 5 > [(t+1/t)^2+6]/(t+1/t) = 5 > (t+1/t)^2 -5 (t+1/t) + 6 = 0 > t+1/t = 2,3 > x=0 or x = log_2 [(3 +/-sqrt5)/2].
x=0; (log(3+-√5)/ log2)-1
X=0,log((3+√5)/2)/log2
χ=0 διπλη, ή χ=[[log(3+ -ριζα5)]/log2]-1
cant you use hindi sir??
{4^4x^24^6x^2}={ 8^10x^4+2}= 10^10x^4=/{4^6x^2+4x^2}= 8^6x^4 _10^10x^4/8^6^x^4=1.^2^1^.2^6x^1 1^1.2^1^1^1.2^1^3^2x1^1 11 x3^2 x^3^2.(x ➖ 3x+2 )
2^x = u
(u⁴ + 8u² + 1)/(u³ + u) = 5
[(u² + 1)² + 6u²]/(u³ + u) = 5
(u² + 1)/u + 6u/(u² + 1) = 5
(u² + 1)/u = w
w + 6/w = 5
w² - 5w + 6 = 0
(w - 2)(w - 3) = 0
w = 2
(u² + 1)/u = 2
u² - 2u + 1 = 0
(u - 1)² = 0 => u = 1
2^x = 1 => *x = 0*
w = 3
(u² + 1)/u = 3
u² - 3u + 1 = 0
u = (3 ± √5)/2
2^x = (3 ± √5)/2
2^(x + 1) = 3 ± √5
(x + 1)ln2 = ln(3 ± √5)
*x = (1/ln2)ln(3 ± √5) - 1*
X=0
X=0,
