Simplify a radical with a number and variable as radicand
Test your understanding of simplify a radical with variables by practicing it! Work through the below exercises to use it in practice.
🎙️
Let's simplify the radical 18 'K' to the power of 3
🎙️
Let's factor both the 18 and the 'K' so we can see if there are any squared factors.
🎙️
There's a 3 squared and a 'K' squared. If we bring those out we have a simplified radical of 3 'K', times the square root of 2 'K'
