Answer 1

3log 36 - 4 9log 30 + 16. 81log√15 =
= 3log6² - 4 3²log3.10 + 16.3^4log (3.5)^1/2
= 2.3log 6 - 4.1/2.(3log3 + 3log10) + 16.1/4.1/2.(3log3+ 3log5)
= 2.3log6 - 2(1+3log10) + 2(1+3log5)
= 2.3log 6 - 2 - 2.3log10 + 2 + 2.3log5
= 3log36 - 3log100 + 3log 25
= 3log36.25/100
= 3log9
= 3log3²
= 2

 =
= 60log3 + 60log4 + 60log5
= 60log3.4.5
= 60log60
= 1
