**Wobb**, Thursday, February 14, 2013 at 10:31amLCD: 3 * 4 * 11 * 7 = 924

so...

2/3 = 2(308)/924 = 616/924

3/4 = 3(231)/924 = 693/924

2/11 = 2(84)/924 = 168/924

5/21 = 5(44)/924 = 220/924

if you can't get the answer from those, then go to your teacher for help...immediately !!

one problem at a time.

a^4 = (2/5)^8 = 2^8/5^8

b^2 = (8/5)^10 = 2^30/5^10

c^2 = (4/5)^20 = 2^40/5^20

a^2b/c = 2^(8+30-40)/5^(8+10-20) = 2^-2/5^-2 = 5^2/2^2 = 25/4
