You can put this solution on YOUR website! log5+logx=2?
remember: logs can be combined as such: Log(x) + Log(y) -> Log(x*y)
so: log(5) + log(x) = 2
becomes: log(5*x)=2 or log(5x)=2
logs can be changed into exponents, and "log" is base 10.
so: log(5x)=2 becomes: 5x= {10^2} (10^2 = 10 squared)
5x= {10^2}
5x=100
divide both sides by 5
x=20
You can put this solution on YOUR website! Find the value of x: Apply the "product rule" for logarithms: to get: Rewrite this in "exponential" form: ---> to get: Divide both sides by 5: so...
Check: = 2
