# Algebra

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)

1. 1. 0.45
2. 4sqt5 +9
3. -6sqt10 -75
4. 13sqt3 + 7sqt30
