let `delta = |(log(7/15),log49, log 49),(log 25, log(5/.21), log (25)),(log 9 , log 9 ,log 3/35)|` then `delta` is equal to

Suppose a,b,cgt1 . Let Delta=|(loga,logb,logc),(log(2007a),log(2007b),log(2007c)),(log(2017a),log(2017b),log(2017c))| then Delta is equal to

Delta=|[log x ,log y, log z],[log 2 x, log 2 y, log 2 z],[log 3 x, log 3 y, log 3 z ]|=

Suppose a,b,c epsilon R and a,b,c gt 0 . Let Delta=|(loga, logb, logc),(log(7a),log(49b),log(343c)),(log(3a),log(9b),log(27c))| then Delta is equals to

If log_7 2=a , then log_(49)28 is equal to

Find x if 2 log 5 + (1)/(2) log 9 - log 3 = log x

If 3 +"log"_(5)x = 2"log"_(25) y , then x equals to

If 3 +"log"_(5)x = 2"log"_(25) y , then x equals to
