Answer:

There are multiple ways to go about doing this. The first method that I thought of is to start by looking at the fraction like so:

3–√−2(2+3–√)−7–√

From this, it makes sense to try multiplying the numerator and the denominator by (2+3–√)+7–√ , giving

3–√−2(2+3–√)−7–√×(2+3–√)+7–√(2+3–√)+7–√=23–√+3+21−−√−4−23–√−27–√(2+3–√)2−7=−1−27–√+21−−√43–√.
