Question

How do you multiply `-7sqrt3 *2sqrt10`?

Answer 1

`-14 sqrt(30 )`

Explanation:

This is a binomial separated by a multiplication sign.

To handle this:

1. multiply everything NOT under the square root signs or radicals
2. multiply everything under the radicals
3. combine (by multiplying those two terms together):

`-7 xx 2 = -14`

`sqrt(3) xx sqrt(10) = sqrt(30)`

Since `sqrt(30)` cannot be simplified, `-14sqrt(30)` is the answer.
