Question

What’s the extraneous solution of 3^2x=30

Answer 1

Greetings! Lets solve this shall we?!

Lets begin with

3^2x = 30

Then, we must natural log (ln) or regular log (log) both sides to obtain

ln3^2x = ln30......................Then bring the 2x down via power rule of logarithms

2xln3 = ln30.........................Then we divide 2ln3 to both sides to obtain

x = (ln30) / (2ln3)

I hope this helps!
