Answer: C
Step-by-step explanation:
C is 30 StartRoot 3 EndRoot minus 21 StartRoot 6 EndRoot and that is 60/3-21/5
The product of the radical function is 15 StartRoot 12 EndRoot minus 21 StartRoot 6 EndRoot
Product of radicals
Given the following products
[tex]3\sqrt{2}(5\sqrt{6}-7\sqrt{3})[/tex]
Expand the expression to have:
[tex]3\sqrt{2}(5\sqrt{6}-7\sqrt{3})\\15\sqrt{12}-21\sqrt{6}\\[/tex]
From the given expansion, the product of the radical function is 15√12 - 21√6
