Answer:
2
Step-by-step explanation:
To find the value of \( x \) in the equation \( x^3 + 1 = 9 \), follow these steps:
1. Subtract 1 from both sides of the equation to isolate the \( x^3 \) term:
\[
x^3 + 1 - 1 = 9 - 1
\]
\[
x^3 = 8
\]
2. Take the cube root of both sides to solve for \( x \):
\[
x = \sqrt[3]{8}
\]
3. Simplify the cube root:
\[
x = 2
\]
Therefore, the value of \( x \) is \( 2 \).
Answer:
To solve the equation x^3 + 1 = 9 we first subtract 1 from both sides:
x^3 = 9 - 1
x^3 = 8
Now, to find the value of x, we take the cube root of both sides:
x = square root of 8
x = 2
So, the value of x in the equation is 2.
