Quick plz which equation can be used to find the solution of (13)d−5=81(13)d−5=81 ? a: d+5=4 b: -d+5=4 c: d-5=4 d: -d-5= 4

Your question:   Which equation can be used to find the solution of (1/3)^d−5^=81?

Just so you know: I already know someone else has answered, but I decided to give a answer that might help a bit more.. mate.

First explanation: In order to find out what "D" means, you have to  create equivalent expressions in the equation that all have equal bases, then solve for  d .

Second explanation: To find the solution on each answer you must  move all terms not containing  d to the right side of the equation.
