Solve 5^(8 x − 8) = 8^(3 x − 3) for x

I cant get this, please help with steps, thank you.-Indices and logs are linked together and sometimes using logs really simplifies the question instead of using the rules of indices to solve for x J

General formula for a second derivative

Im struggling trying to find the second derivative of f(x)=x^4*e^x Ive found f (x)= e^x*x^3(4+x) using the product rule. Im not very good with the dy/dx notations yet and have been using u, v, u

Solving Quadratic Equations with Inequalities; Is my answer correst

2k^2-5k+2≤0 Factorise to get (2k-1)≤0 and (k-2)≤0 k=0.5 or k=2 So my answer would be 0.5≤0≥2, is that correct?-If you factorize the equation becomes (2 k -1 ) ( k - 2) ≤0 But this does NOT mean (2 k

Rewrite the expression ln9+4lnx+6ln(x^2+6) as a single logarithm lnA. Then the function

ln(9) + 4*ln(x) + 6*ln(x^2 + 6) = ln(9x^4) + ln(x^2 + 6)^6 = ln(9*(x^3 + 6x)^4* (x^2 + 6)^2)-ln9 + 4lnx + 6ln(x^2+6) ln9 + ln(x^4) + ln((x^2+6)^6) [carry out all power properties] ln((9)(x^4)(x^2+6)

I have to solve 4 - x - 3x^2, but isn't this problem backwards

Looks backwards Turn it around.......Anytime the first term is negative, factor out a negative 4 - x - 3x^2 -3x^2 - x + 4 -1(3x^2 + x - 4).............Now factor........bring down the - ANSWER...

Integration with respect to ln(x)

How do you integrate INT[ 1 * d(ln(x))] So its not with respect to x, its with respect to ln(x)-If u is any integrable function, then : INT [ (1)du ] = u + c. ......................................…

Calc help, please and thank you :)

Im not sure what Im doing wrong, but the site Im on tells me that it isnt correct. For f(x)=csc(x) + 5 sec(x) find f (x) I got -cscxcotx + 5secxtanx How is this not correct? Also for f(x) = (tanx -
