Question 328569: is this true or false: 3log(b)√3:(a)=log[b](a)
assume that x,y,z are positive numbers. use the properties of logarithms to write each expression as the logarithm of one quantity: log%28b%2C%28x%29%29%2Blog%28b%2C%28x%2B2%29%29-log%28b%2C%288%29%29
solve each equation. if answer not exact, give in four decimal places:
3%5E%28x%2B3%29=3%5Ex=84 hint:3%5E%28x%2B3%29=3%5E%28x%29%283%29%5E3

write in terms of the logarithm x,y,and z: log%28b%2C%283xy%29%29

Two of your problems contain errors in typing so that we cannot help you
with them unless you repost and type them correctly. I will do the ones
which make sense.

is this true or false:
3log%28b%2C%28sqrt%283%29%29%29%22%3A%22%28a%29=log%28b%2C%28a%29%29

That one doesn't make any sense.  Why did you put a colon between the
expression on the left and the equation on the right?  

-------------------------------

assume that x,y,z are positive numbers. use the properties of logarithms to write each expression as the logarithm of one quantity:
log%28b%2C%28x%29%29%2Blog%28b%2C%28x%2B2%29%29-log%28b%2C%288%29%29

Use the logarithm identity log%28P%2C%28Q%29%29%2Blog%28P%2C%28R%29%29=log%28P%2C%28QR%29%29 

on the two highlighted terms below:

highlight%28log%28b%2C%28x%28x%2B2%29%29%29%29-log%28b%2C%288%29%29

log%28b%2C%28x%28x%2B2%29%29%29-log%28b%2C%288%29%29

Use the logarithm identity log%28P%2C%28Q%29%29-log%28P%2C%28R%29%29=log%28P%2C%28Q%2FR%29%29 on that:

log%28b%2C%28x%28x%2B2%29%2F8%29%29

-----------------------------

solve each equation. if answer not exact, give in four decimal places:
3%5E%28x%2B3%29=3%5Ex=84 hint:3%5E%28x%2B3%29=3%5E%28x%29%283%29%5E3


That first equation has two equal signs.  One of them should have been either
a + or a - but I can't tell which one should have been which one.

-----------------------------

write in terms of the logarithm x,y,and z:
log%28b%2C%283xy%29%29

Use the logarithm identity log%28P%2C%28QRS%29%29=log%28P%2C%28Q%29%29%2Blog%28P%2C%28R%29%29%2Blog%28P%2C%28S%29%29 

log%28b%2C%283xy%29%29=log%28b%2C%283%29%29%2Blog%28b%2C%28x%29%29%2Blog%28b%2C%28y%29%29

-----------------------------

write in terms of the logarithm x,y,and z: 



Use the logarithm identity log%28P%2C%28QR%29%29=log%28P%2C%28Q%29%29%2Blog%28P%2C%28R%29%29 



Use the logarithm identity log%28P%2C%28Q%5ER%29%29=R%2Alog%28P%2C%28Q%29%29 on both terms:

1%2F2log%28b%2C%28x%29%29%2B3log%28b%2Cy%29
