To subtract 7√5 - 4√5, you need to simplify the terms with the same radical (√5).
Step 1: Start with the given expression: 7√5 - 4√5.
Step 2: Since both terms have the same radical (√5), you can combine them. Subtract the coefficients: 7 - 4 = 3.
Step 3: Copy the common radical (√5) and multiply it by the result of the coefficients: 3√5.
Therefore, the difference between 7√5 - 4√5 is 3√5.
