To solve the equation \( x^{1/5} = 6 \), you need to isolate \( x \). To do this, raise both sides of the equation to the power of 5:
\[ (x^{1/5})^5 = 6^5 \]
This simplifies to:
\[ x = 6^5 \]
Now, calculate \( 6^5 \):
\[ 6^5 = 6 \times 6 \times 6 \times 6 \times 6 = 7776 \]
So the missing value is:
\[ x = 7776 \]
