In need of lots of help!
lets start with:
algebra - working with exponents and logarithms-
question five
solve (for x)
2log3(x)=5
answer D x = 9square root(3)
i presume the 2 means that x is squared in the question?
please explain what 9square root of (3) is and how it is the square root of 243?
thank you ....

Divide both sides by 2
3^x both sides.
Welcome to the forum, young man.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
