Solve... (V`7)(4 + V`3)

* The radical sign is represented as (V`)

First: multiply the outer term with the terms in parenthesis...

(V`7)(4) + (V`7)(V`3)

4V`7 + V`21

ken, you forgot to take the square root of 7
so its 4rt7+rt21

unless you ment the sq rt of the whole thing: sqrt(28+7rt3) cant really be simplified

7 ( 4 + sqrt(3) = 7*4 + 7*sqrt(3) = 28 + 7*sqrt(3)
