Question

Solve by taking the a logarithm of both sides.

8x = 23
x = 1.21

x = 1.51

x = 1

x = 2
x = 1.21

x = 1.51

x = 1

x = 2

Answer 1

what are all those things below, choices?

Answer 2

\[b^x=A\iff x=\frac{\ln(A)}{\ln(b)}\]

Answer 3

sorry
x = 1.21

x = 1.51

x = 1

x = 2
those are the choices

Answer 4

i take it the equation is
\[8^x=23\]

Answer 5

yes

Answer 6

if so, clearly the last two options are out, since \(8^1=8\) and \(8^2=64\)

Answer 7

take a calculator and compute
\[\frac{\ln(23)}{\ln(8)}\] for your answer

Answer 8

it wont let me
