Question

3 в степени ×-3 =81

Answer 1

3^x-3=3^4
x-3=4
x=4+3
x=7

Answer 2

It looks like there might be some confusion in your expression. If you meant "3^x * -3 = 81," we need to find the value of 'x' that satisfies this equation.

To solve this equation, let's isolate the term with 'x' on one side of the equation:

3^x * (-3) = 81

First, divide both sides by -3:

3^x = 81 / (-3)

Now, simplify the right-hand side:

3^x = -27

Since 3 raised to any real number will always be positive, there are no real values of 'x' that satisfy this equation. The equation has no real solutions.

If you meant something else, please clarify the expression, and I'll be happy to assist further.
