Find x so that (5/3)^(5)xx(5/3)^(11)=(5/3)^(8x)

Find x such that (frac(3)(5))^(3) xx (frac(3)(5))^(-6)=(frac(3)(5))^(2x-1).

Find the value of x so that (5/3)^(-2)xx(5/3)^(-14)=(5/3)^(8x)

Find x: (2/5)^(2x+6)xx(2/5)^3=(2/5)^(x+2)

Find (dy)/(dx) , when: y=(2x+3)^(5)(3x-5)^(7)(5x-1)^(3)

Find the value of x for which ((5)/(3))^(-4)times((5)/(3))^(-5)=((5)/(3))^(3x)

Evaluate : ((6)/(7))^(2)times((6)/(5))^(-3)times((7)/(5))^(2)

Using appropriate properties find. (i) -(2)/(3)times(3)/(5)+(5)/(2)-(3)/(5)times(1)/(6) (ii) (2)/(5)times(-(3)/(7))-(1)/(6)times(3)/(2)+(1)/(14)times(2)/(5)

-(2)/(3)times(3)/(5)+(5)/(2)-(3)/(5)times(7)/(6)

Evaluate : (5/7)^3 times ( 5/7 )^(-6) times ( 1/3 )^(-2 ) times ( 3/5 )^-2
