A

Concepts

1

Which statement correctly describes 25\sqrt{25}?

2

A student solves x3=8x^3 = 8. How many real solutions does this
equation have, and what are they?

3

A student computes 2≈1.414\sqrt{2} \approx 1.414 on a calculator and
argues that 2\sqrt{2} must be rational, since 1.414 is a
terminating decimal. What is wrong with this reasoning?

B

Procedures

1

Solve x2=81x^2 = 81. Enter both solutions separated by a comma, with
the positive value first (for example: 5,-5).

2

Solve x3=27x^3 = 27. Enter the value of xx.

3

Evaluate 121\sqrt{121}.

4

Evaluate 643\sqrt[3]{64}.

5

Evaluate 916\sqrt{\dfrac{9}{16}}. Write your answer as a fraction.
