Question

Solve 8^x=12143

Answer 1

here's a hint \[\huge a^b = c \implies \log_a c = b\]
for example: \[\huge 2^x = 4 \implies \log_2 4 =x\]
does that help?

Answer 2

So logbase8ofx=12143 for the start up?

Answer 3

nope. look closely at what i did.

Answer 4

when i changed it into logarithm, the exponent was moved to the right side

Answer 5

logbase8of12143=x?

Answer 6

right!

Answer 7

AWESOME, thanks for the help.

Answer 8

now here comes the last part... in my example i had \[\log_2 4 = x\] to get the exact value of x, \[\log 4 \div \log 2\]
