If `"log"_(2) 7 = x`, then x is:

If log_(2)x + log_(2)x=7 , then =

If log_(y)x +log_(x)y = 7 , then the value of (log_(y)x)^(2) +(log_(x)y)^(2) , is

If log_(y)x +log_(x)y = 7 , then the value of (log_(y)x)^(2) +(log_(x)y)^(2) , is

If log_(y)x +log_(x)y = 7 , then the value of (log_(y)x)^(2) +(log_(x)y)^(2) , is

If y=log(x^2+7x) , then dy/dx=?

If log_y x +log_x y=7, then the value of (log_y x)^2+(log_x y)^2, is

If log_(y)x+log_(x)y=7, then the value of (log_(y)x)^(2)+(log_(x)y)^(2), is

If 2^(x)*3^(x+4)=7^(x), then x is equal to (A) (4log3)/(log7-log6)(B)(4log3)/(log6-log7)(C)(2log3)/(log7-log6)(D) none of these

If log_(2)[log_(7)(x^(2)-x+37)]=1 , , then what could be the value of x ?
