Question

14 to the 7x power = 21

Answer 1

do you mean \[\large 14^{7x} = 21\]

Answer 2

YES thanks :D

Answer 3

turn it into logarithmic form..that will give you \[\Large \log_{14} 21 = 7x\]

Answer 4

get the value of \(\log_{14} 21\) first then divide by 7...got it?

Answer 5

yes! So, like Log(14)21 = 24.06... then /7 = 3.43...

Answer 6

let me check...wait..

Answer 7

did you do \[\large \log 21 \div \log 14\] on your calculator?

Answer 8

no i did Log(14)21... that wrong?

Answer 9

you need to do it like i said...that's how you do logs on calculator \[\large \log_a b = \log b \div \log a\] got it?

Answer 10

How do I do Log_a

Answer 11

on a calculator?
