If `a^x=b^y ,` then a. `log\ a/b=x/y` b. `(loga)/(logb)=x/y` c. `(loga)/(logb)=y/x` d. none of these

If a^(x)=b^(y), then a.log backslash(a)/(b)=(x)/(y)b(log a)/(log b)=(x)/(y) c.(log a)/(log b)=(y)/(x)d .none of these

If a^x=b^y=c^z=d^w then log_a(bcd)=

If a^2+b^2=18ab ,then prove that log((a-b)/4)=1/2(loga+logb)

If a^(2)+b^(2)=23ab prove that log""(a+b)/5=1/2(loga+logb)

If a^(2)+b^(2)=23ab , then prove that log(a+b)/5=1/2(loga+logb)

The value of loga b-log|b|= loga (b) "log"|a| (c) -loga (d) none of these

The value of loga b-log|b|= (a) loga (b) "log"|a| (c) -loga (d) none of these

If a^2+b^2=23 a b , then prove that log((a+b))/5=1/2(loga+logb)dot

Prove: log_b b^x=x
