Question

log2+logx=log32

Answer 1

does x=30? that seems far too easy.

Answer 2

2x = 32

x = 16

Answer 3

log 2x = log 32
2x = 32
x = 16

Answer 4

Use:

\[Loga + Logb = Log(ab)\]

Answer 5

\[\implies Log2x = Log32 \implies 2x = 32 \implies x = 16\]

Answer 6

So it was too easy to be true. So when it's logs it multiplys together? in this format that is.

Answer 7

I have written the formula above..
If the question is given in that form then you can use this..

Answer 8

you need to know laws of logs
log a + log b = log ab
log a - log b = log a/b
and log a^n = n log a

Answer 9

Thank you. you were both a very big help but cwrw238 was a little clearer.

Answer 10

\[Loga + Logb = Log(ab)\]
\[Loga - Logb = Log(\frac{a}{b})\]
\[Logx^n = n.Logx\]
