HELP?!
1.9^2
2.(5x^9y)(2x^2y^3)
3.(a^1b^2) / (a^2b^4)
4.(7x^1/y^4)^2
Scientific notation:
5)
.0000745
Decimal Form:
6)
9.3*10^6
Solve:
7.3√27
8.√(5a)^2
Simplify:
9.√60x^5y^2
10.√75x^3 / √3x

Math 
Steve,
1. 9^2 = (9^2) = 81
2. 10 x^7 y^2
3. a^3 b^6
4. (7 x^1 y^4)^2 = 1/49 x^2 y^8
5. 7.45*10^5
6. 9,300,000
7. 3√27 = 3√9√3 i = 9√3 i
8. √(25a^2) = 5a (note the "" sign gets lost)
9. 2 x^2 y √15x
10. 5x
As usual, check my math. If something's not clear, come on back.
