I have a Texas Instruments-30Xa calculator. I am not getting the answer that the online course is providing.

okay so the question is (7log2)-(log3)+(6log5)/ (2log5)-(log2)+log7. I understand the problem but I am not getting the right answer b./c I don't know which is the right order to press the buttons or which buttons I have to press to get the right answer.

It's ok. I think I figured it out.

It looks like you need to use brackets, because no-one can
tell from that expression, what's multiplied, divided or
subtracted from what.

7log2 - log3 =
log2^7 - log 3 =
log(2^7/3) = log42.666666......= 1.630088
NB The Draughting of your question leaves queries???? I have done what I think is the first part, but the second/third parts are not clearly understood. Is the last part (log2) x (log7) or is it log (2^(log7)).Please use brackets to clarify.
