Simplify a radical with a number and variable as radicand
This math skill teaches how to simplify a radical expression that includes both a numerical coefficient and a variable term. The process involves factoring out the perfect squares from both the number and variable, then moving them outside the radical.
🎙️
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'
