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.

first one because it can't have a fraction in it

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
