Question

solve the given exponential equation


​

Answer 1

Step-by-step explanation:

3 to the power 4x=1/81

1/81=3 to the power -4

then,

3 to the power 4x=3 to the power-4

4x=-4

x=-4/4=-1

Answer 2

Answer:

ans is -1

Step-by-step explanation:

3^4x=1/81

=1/3^4

3^4x=3^-4. (because a^-m=1/a^m)

as bases are equal powers are also equal

so,

4x=-4

X= -4/4=-1

therefore, X=-1
