Solving the Equation (x+5)^4 = 16
This equation involves a fourth power, which might seem intimidating at first, but we can solve it systematically. Here's how:
1. Isolate the Term with the Variable
Start by taking the fourth root of both sides of the equation:
(x+5)^4 = 16 (x+5) = ±√[4]16 (x+5) = ±2
We get two possible solutions because the fourth root of a number can be positive or negative.
2. Solve for x
Now, we have two separate equations to solve:
- x + 5 = 2
- x + 5 = -2
Solving for x in each equation:
- x = -3
- x = -7
Conclusion
Therefore, the solutions to the equation (x+5)^4 = 16 are x = -3 and x = -7.
