Ive been trying to complete a revision sheet but it has logarithims and index laws, and i don't know how to do them. Ive included a few of the hardest questions frome the revision sheet in the attachment.

..........Look at attachment.............

I've tried the first question fir the logs:

Log 6 + Log 4

So i separated the two logs and didthem sepratly:

Log 6

x = Log^10 (6)

10^x = 6?

Log 4

x = Log^10 (4)

10 = 4 ???

Then i get stuck there, could someone please show me an example so i can attempt the rest of the questions on the sheet.

And with the index laws i couldn't even start, had no idea wat to do.

can someone please help!!!!
