Tìm x

To solve the given equations:

5) x¹ = 16
To solve for x, we need to isolate it. We can do this by dividing both sides of the equation by 1:
x = 16

7) (x-3) = 6
To solve for x, we need to isolate it. We can do this by adding 3 to both sides of the equation:
x - 3 + 3 = 6 + 3
x = 9

(x+2) = 36
To solve for x, we need to isolate it. We can do this by subtracting 2 from both sides of the equation:
x + 2 - 2 = 36 - 2
x = 34

9) 25x² = 25
To solve for x, we need to isolate it. We can do this by dividing both sides of the equation by 25:
25x²/25 = 25/25
x² = 1
Taking the square root of both sides gives us:
x = ±1

10) (x-1)* = 16
It seems like there is a missing value or operation in this equation. Please provide the missing information or clarify the equation.

15.24 - 14.5 (145:5)
To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS). First, we perform the division inside the parentheses:
145/5 = 29
Then, we subtract 14.5 from 15.24:
15.24 - 14.5 = 0.74

Therefore, 15.24 - 14.5 (145:5) = 0.74.
