Video Summary

To determine which expression has the largest value, we can square each one to simplify the comparison, as the square root preserves order. After squaring, we calculate: <br /><br />- From A, we get 20 times 13.<br />- From B, we have 20 squared times 13, which is 400 times 13, equating to over 4,000.<br />- From C, this value is larger than any other calculated expression.<br />- From D, 201 times 9 is approximately 1,809, which is smaller.<br />- From E, the result is 2013, which is also smaller than 4,000.<br /><br />Thus, the largest value corresponds to option C, 20 times the square root of 13.
