Answer:

t=40.5

Step-by-step explanation:

T likely stands for time. but I suspect you haven't given us the full question because the piece you gave us doesn't determine what T stands for. either way, t is your variable. could be substituted for x or any other variable.

t2=81

isolate t

/2

t= 81/2

t= 40.5

Plz help what is the answer.

The answer is A.

You can recognize the pattern of an exponential equation to know the answer, but to prove it, the easiest way is to inspect the elements and find exponential.

In this case, y = 2^x power
2^1 = 2
2^3 = 8
2^5 = 32
2&7 = 128

That is the best reason for the answer I can give sadly.
