Question

3^4-х=27математика помогите

Answer 1

$3^{4-x}=27\\3^{4-x}=3^3\\4-x=3\\x=1$

Answer 2

To solve the equation 3^4 - x = 27, we need to find the value of x.

Step 1: Simplify the equation

First, let's simplify the left side of the equation. 3^4 means 3 raised to the power of 4, which is equal to 81. So, the equation becomes:

81 - x = 27

Step 2: Solve for x

To solve for x, we need to isolate it on one side of the equation. Let's subtract 27 from both sides:

81 - x - 27 = 27 - 27 54 - x = 0

Now, let's isolate x by subtracting 54 from both sides:

54 - x - 54 = 0 - 54 -x = -54

To solve for x, we need to multiply both sides by -1 to get rid of the negative sign:

(-1)(-x) = (-1)(-54) x = 54

Answer:

The value of x that satisfies the equation 3^4 - x = 27 is x = 54.
