Test 6 : Exponents
		Note: in the following problems /N means square root of N. I could not typeset radical signs. 1) What is 3-3 ?     1/33 = 1/27      Hint:  2-2 = 1/4       2) Simplify  (a7b-2) / (b2a8)?      1/ab4 or  b-4/a            Hint:   c2/c3 = 1/c 3) What is  150%  of 641/2 ?         1.5 (8) = 12      Hint:  x1/2 = square root of x. 4) Simplify    /12  +   /75    =   7 /3      Hint: /20 = 2  /5 5) What is  (20 + 30)3 ?   23 = 8      Hint:  x0 = 1  for all x = 0. 6)  Simplify    /(8 x2) ?  2 sqrt(2) x      Hint: take everything that is a perfect square out of the radical. 7)  What is 323/5 ?       8      Hint:  Take the fifth root of 32, then cube it. 8) What is   4/(16a1/3 / a1/4) ?       = (16a1/3 / a1/4)1/4     = (16a1/12)1/4     = 2a1/48         Hint:  a1/3 / a1/4  =  a(1/3 – 1/4)    9) What is  (0.001)-2/3 ?    100  Hint: Take the cube root of 0.001, then square it. 10)  Arrange these from least to greatest:  22/3 ,  23/2,  (½)½,  (½)2,  (½)-2    Answer   (½)2,  (½)½ , 22/3 ,  23/2 ,  (½)-2   Hint:  square root of 2   =  1.414…
