To expand and simplify the expression 4√7(2√3 + 3√6 - √7), you need to distribute the 4√7 to every term inside the parentheses.
Let's go through it step by step:
Step 1: Distribute 4√7 to 2√3:
4√7 * 2√3 = 8√21
Step 2: Distribute 4√7 to 3√6:
4√7 * 3√6 = 12√42
Step 3: Distribute 4√7 to -√7:
4√7 * -√7 = -4√49
Now, you can combine these simplified terms:
8√21 + 12√42 - 4√49
The expression is now simplified and cannot be simplified any further.
So, your final answer is: 8√21 + 12√42 - 4√49.
