Question 958246: HOW DO I SOLVE THESE 3 QUESTIONS? AND WHAT ARE THE ANSWERS?
1.Choose values for n and x so that n *square root sign* of x is
a) a whole number
b) a rational number
c) an approximate decimal
2) Simplify the following. Simplified answers need to be written with positive exponents
a) 3x^4 5x^6
b) 3x^5/9x^-4
c) 1/5a^-3
3) Simplify the following. Simplified answers need to be written with positive exponents
a) (3a^3b^-2)^2(15a^-2b^3)
b) 10a^2(a^3)^2/2a
c) (-2xy^4)^3

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]
