Solve for x.
`x=sqrt(20)xxsqrt5`

Answer

To solve the equation \( x = \sqrt{20} \times \sqrt{5} \), we can follow these steps:

### Step 1: Combine the square roots
We can use the property of square roots that states \( \sqrt{a} \times \sqrt{b} = \sqrt{a \times b} \). Therefore,
\[ x = \sqrt{20} \times \sqrt{5} = \sqrt{20 \times 5} \]

### Step 2: Calculate the product inside the square root
Now, we calculate \( 20 \times 5 \):
\[ 20 \times 5 = 100 \]
So, we have:
\[ x = \sqrt{100} \]

### Step 3: Simplify the square root
Now, we can simplify \( \sqrt{100} \):
\[ \sqrt{100} = 10 \]

### Conclusion
Thus, the value of \( x \) is:
\[ x = 10 \]
