Question

Solve each equation

Answer 1

\[6^{x} = 444\]

Answer 2

\[4\log_{3} 2x - 2\log_{3} x = 1\]

Answer 3

log(5x - 4 ) = 3

Answer 4

\[6^{x}=444\]
x log6=log444
x=log444/log6
x=3.4021444667 using calculator.
Did you follow with understanding?

Answer 5

Do you have an \[x ^{y}\]
function key on your calculator, you then can check it.

Answer 6

\[6^{3.402144466}=444\]

Answer 7

I won't go any further until you understand this one, monologs are no fun.

Answer 8

For my own curiosity, is the third one (last) logs to the base 2???\[\log _{2}(5x-4)=3\]

Answer 9

no it's base 10

Answer 10

Hmmmmm I cannot come up with their answer to the last one, I will be thinking bout that one while you try and understand the answer to the first one.

Answer 11

O.K I got it for the last one. Let me know if you followed the first one with understanding.

Answer 12

i understand the first one, you divided the logs to get x

Answer 13

Yes, and a hint for the last one. Log(5x-4)=3 antilog 3 = 1000

Answer 14

\[4\log _{3}2x-2\log _{3}x=1\]
\[(2x)^{2}/x ^{2}=1\]
\[((16x ^{4})/(x ^{2}))=1\]
\[16x ^{2}=1\]
\[x ^{2}=1/16\]
\[x=\sqrt{1/16}=\pm1/4\]

Answer 15

*That 2nd line should be\[(2x)^{4}/x ^{2}=1\]

Answer 16

typo u know

Answer 17

thanks a ton!
