PLEASE HELP, I WILL MEDAL/FAN
2logx = log2 + log (3x-4)
Is this Calculus?
Solve for x: 2%2Alog%28%28x%29%29=log%28%282%29%29%2Blog%28%283x-4%29%29 Use this rule of exponents on the left side A%2Alog%28%28B%29%29=log%28%28B%5EA%29%29 log%28%28x%5E2%29%29=log%28%282%29%29%2Blog%28%283x-4%29%29 Use this rule of logarithms on the right side: log%28%28A%29%29+%2B+log%28%28B%29%29+=+log%28%28AB%29%29 log%28%28x%5E2%29%29=log%28%282%283x-4%29%29%29 Distribute on the right: log%28%28x%5E2%29%29=log%28%286x-8%29%29%29 Use the rule: The equation log%28%28A%29%29 = log%28%28B%29%29 is equivalent to the equation A=B x%5E2=6x-8 x%5E2-6x%2B8=0 %28x-2%29%28x-4%29=0 x-2=0 gives solution x=2 x-4=0 gives solution x=4
Sorry computer = slow -_-
Its pre calculus @Austin1617
nothing is showing up for what you wrote??
hold on
ok
So after you get the trinomial "\[x^2-6x+8\]" set it equal to zero then set each binomial equal to zero and: voila! x-2=0 gives solution x=2 x-4=0 gives solution x=4
Remember: log(A)+loh(B)=log(AB)
