I need some help figuring these.

Compute each product and simplify the result. I don't have the squareroot sign so put that meaning that's where it goes with the number after it.

1. (0.3 Squareroot of 5)^2

2. (2+ squareroot of 5)^2

3. (5+4Squareroot of 10)(1-2 squareroot of 10)

4. (3 squareroot 5 + 4 squareroot 2)(squareroot 15+ squareroot 6)
