Given that logk 2=0.389 and logk 7=1.453, find logk 98.

Given that logk 2=0.389 and logk 7=1.453, find logk 98.

I tried multiplication and exponents as well as addition of both and I couldn't find a formula to make those to logs work for logk 98. So would my answer be that I can't find logk 98 using these properties?

Since log rules are exactly what is needed to find the answer to this exercise, it would be very helpful if you showed what you'd done, so we could correct any errors. :idea:

Please be complete. Thank you!

I think I just figured it out.

logk 98=logk (2x49)=logk 2 + logk 49

logk 2 + logk 7^2= logk 2 + 2logk7=0.389 +2(1.453)=3.295

Is that correct?

Looks good to me!
