A Review of Algebra

RADICALS

1. Review all definitions in Radicals, also the methods of transforming and simplifying radicals. When is a radical in its simplest form?

2. Simplify (to simplest form):

3. Reduce to entire surds:

4. Reduce to radicals of lower order (or simplify indices):

5. Reduce to radicals of the same degree (order, or index): and and and and and

6. Which is greater, or ? or ?

7. Which is greatest, or ? Give work and arrange in descending order of magnitude.

Collect:

11. A and B each shoot thirty arrows at a target. B makes twice as many hits as A, and A makes three times as many misses as B. Find the number of hits and misses of each. (Univ. of Cal.)
