@smackdownbb4 11^x=11000
1-put log in both side:
log 11^x=log 11000 then......
x log 11=log 11000
divide both side by log 11
x=3.88
now check:
11^3.88=10988 which aproximatly equals 11000.
hope that was helpful!

how would you do 2logx(squared) - 3logx = 0
GeorgiaRoseWhittle 1 month ago
@GeorgiaRoseWhittle: If only the x is squared, use the power property first, then combine like terms, then rewrite as an exponential equation and solve. I don't do the problem for you, but I do examples like this if you watch the full set of 24 logarithmic videos. You can search by topic on my website to narrow it down.

how do you solve 11^x = 11000 using common or natural logarithm
smackdownbb4 1 year ago
@smackdownbb4: keep watching...this problem is covered on logarithms part 15. Watch part 14 first. See my videos on my website listed on video. Go to math videos, algebra, logarithms, and you can see what is covered on each video.

how do you simplify e^(3/x)
mjacob60 1 year ago
@mjacob60: It IS simplified. You didn't write an equation, so you can't solve it. You can't solve it. It's just an expression with a variable in the exponent....just like 2x + 3 is an expression.
