Solution Steps
Step 1: Solve the Equation
We start with the equation:
\[
5x^{3/2} - 35 = 0
\]
To isolate \(x^{3/2}\), we add 35 to both sides:
\[
5x^{3/2} = 35
\]
Next, we divide both sides by 5:
\[
x^{3/2} = 7
\]
Step 2: Solve for \(x\)
To solve for \(x\), we raise both sides to the power of \(\frac{2}{3}\):
\[
x = 7^{2/3}
\]
Calculating \(7^{2/3}\) gives us approximately:
\[
x \approx 3.6593
\]
Step 3: Check the Solution
We substitute \(x \approx 3.6593\) back into the original equation to verify:
\[
5(3.6593)^{3/2} - 35
\]
Calculating \(5(3.6593)^{3/2}\) results in a value that does not equal 35, indicating that this solution does not satisfy the original equation.
Final Answer
Since the calculated solution does not satisfy the original equation, we conclude that there are no valid solutions. Therefore, the answer is:
