" 1.Evaluate : "(log_(3)135)/(log_(15)3)-(log_(3)5)/(log_(405)3)

let N=((log_(3)135)/(log_(15)3))-((log_(3)5)/(log_(405)3))

let N =(log_(3) 135/log_(15) 3) - (log_(3) 5/log_(405) 3)

Evaluate : 3^(2-log_(3)5)

Let N=(log_(3)135)/(log_(15)3)-(log_(3)5)/(log_(405)3). Then N is a natural number (b) a prime number an even integer (d) an odd integer

7^(log_(3)5)+3^(log_(5)7)-5^(log_(3)7)-7^(log_(5)3)

Evaluate: 2^(log_(3)5)-5^(log_(3)2)

Evaluate: 2^(log_(3)5)-5^(log_(3)2)

let N =(log_(3) 135/log_(15) 3) - (log_(3) 5/log_(405) 3) , then N equals
