Question 958246
1.Choose values for n and x so that n *square root sign* of x is 
a)	a whole number:: n = 3 ; x = 4
---------------------------------------------- 
b)	a rational number:: n = 3 ; x = 4
------------------------------------------------ 
c)	an approximate decimal:: n = 2/3 ; x = 4 

2) Simplify the following. Simplified answers need to be written with positive exponents 
a) 3x^4 5x^6 = 15x^10 
b) 3x^5/9x^-4 = 27x
c) 1/5a^-3 = 1/(5a^3)
------------------------- 

3) Simplify the following. Simplified answers need to be written with positive exponents 
a) (3a^3b^-2)^2(15a^-2b^3) = (9a^6b^-4)(15a^-2b^3
= 135a^4/b
---------------------------
b) 10a^2(a^3)^2/2a = 10a^2*a^6/2a = 5a^7
-------------------------- 
c) (-2xy^4)^3 = -8/[x^3y^12]
