1. Diego squared a number and got 4. Andre squared a different number and got 4. What were the numbers that Diego and Andre squared?
2. Jada squared a number and got -4. Elena squared a different number and got -4. What were the numbers that Jada and Elena squared?

Find all complex solutions to each equation.

1. \(a^2=1\)
2. \(b^2=13\)
3. \(c^2 = \text- 9\)
4. \(d^2 = \text- 5\)

Find the exact solution(s) to each of these equations, or explain why there is no solution.

1. \(\sqrt[3]{a+2}=4\)
2. \(\sqrt[3]{b} +5 = 13\)
3. \(\sqrt[3]{c-1}-14=\text-4\)

Explain how you know that \(\sqrt{\text-1}\) is not a negative number.
