Her words exactly. Now is she looking for 5 multiplied by the square root of 6 in the first set of paranthases and 2 multiplied by the square root of
5 in the second pair? Then add those together? Is that how this works?
Thats assuming the equation survived those copy and pastes from there to here intact, but if it really is
(5 * √6) + (2 * √5)
then this is
12.24744871 + 4.472135955
= 16.71958
There is some uncertainly because if the equation in the original problem is actually
(2 + 3√6) + (4 - 2√5)
then the answer is different because the multiplications of the roots come first.
( 2 + 7.348) + (4 - 4.472)
= (9.348) + (0.472)
= 9.8206
