Answer 2

Answer:

(1) 3 (3) 7log2 (5) 0 (7) 3log2

Step-by-step explanation:

(1) log125/log5

log5³/log5

as, logm ki power n = nlogm

so, 3log5/log5

= 3 ....ans.

(3) log512-log64

log2 ki power 9-log2 ki power 6

9log2-6log2

(9-2)log2

= 7log2 .... ans.

(5) 2log5+log3+log8-1/2log36-log100

log5²+log3+log4×2-log√36-log25×4

as, log(mn) = logm+logn

so, log25+log3+log4×2-log3×2-log25×4

= log25+log3+log4+log2-log3-log2-

log25-log4

so, = 0 ..... ans.

(7) log32+log4-log16

log16×2+log2²-log16

log16+log2+2log2-log16

= 3log2 .... ans.
