Question

Need help with algebra Please!!

Answer 1

1. 4
2. (m*q^2)/(n^4)
3. 4.2*10^-3
4. 6120
5. 4*10^5
6. 8.1*10^7 or 81*10^6
7. 8*16 = 8*8*2 = 64*2 = 128
8. sometimes true. (-2)^-3 = -1/8 and (3)^-3 = 1/27
9. (4)*(x^3)*(y^6)*(x^5)*(y^5) = 4(x^8)(y^11)
10. 8t^9(.16r^2) = 1.28t^9*r^2

Literally just learn how things operate and break them down its not hard. Learn the properties, you will need simple problem solving skills for life.
