" Find "x" if "4^(x)+6^(x)=9^(x)

Solve 4^(x)+6^(x)=9^(x)

6(4^(x)+9^(x))=13.6^(x)

if 4^(x)+6^(x)=9^(x), then find x?

Find the value of x if: (x-4)^3+(x-9)^3+(x-8)^3=3(x-4)(x-9)(x-8)

Find the range of the following functions (i) f(x) = log_(2)(sqrt(x-4) + sqrt(6-x)), 4 le x le 6 (ii) f(x) = 9^(x) - 3^(x) + 1

Evaluate the following limits: lim_(x to 0)(4^(x)-9^(x))/(x(4^(x)+9^(x)))

If x/6+x/4=x/2+3/4, then x= (a) 9 (b) 6 (c) -9 (d) 4
