3(16)^(x)+2(81)^(x)=5(36)^(x)

If (3^(5x)*(81)^(2)*6561)/(3^(2x))=3^(7) then x=

(3^(5x)xx81^(2)xx6561)/(3^(2x))=3^(7), then x=

If (3^(5x)xx(81)^(2)xx6561)/(3^(2x))=3^(7) , then x =_______

If 3^(4x)=(81)^(-1)and(10)^((1)/(y))=0.0001, value of 2^(-x) xx 16^(y) .

(81x^(2)-81)-:(x+1)

If x=3 and y=-1, find the values of each of the using identity: (9y^(2)-4x^(2))(81y^(4)+36x^(2)y^(2)+16x^(4))

If (2/3)^x\ \ (3/2)^(2x)=(81)/(16), . then x= (a) 2 (b) 3 (c) 4 (d) 1

((64)/(27))^((2)/(3))times((9)/(16))^((3)/(2))times((81)/(256))^((3)/(4))=((3)/(4))^(x) then x=

Show that (16(32^(x))-2^(3x-2)*4^(x+1))/(15*2^(x-1)*16^(x))-(5*5^(x-1))/(sqrt(5^(2x))) is given

Factorize: 16a^(2)-(25)/(4a^(2))( ii) 16a^(2)b-(b)/(16a^(2))100(x+y)^(2)-81(a+b)^(2)(x-1)^(2)-(x-2)^(2)
