Where to place the parentheses.
amistre64
  • amistre64
trial and error seems to be the best course of action
ILUVSOCCER
  • ILUVSOCCER
28 b is \[6^{2} \times(2+5)\times20\] Okay, then can you wait till I'm done and see after I'm done with everything?
amistre64
  • amistre64

ILUVSOCCER

@Amistre64?

29A working on it ... 720/2 = 360, so adding to it an multiply it out is just making it bigger 720/9 = 80, and multiply it just gets bigger 720/(a+b*c) seems to be our best route if a+b*x = 72 we got it made right?
amistre64
  • amistre64
a+b*c that is
amistre64
  • amistre64
9*8 = 72 (2+7) * 8 = 72 720/((a+b)*c) seems fair
ILUVSOCCER
  • ILUVSOCCER
Okay, \[720\div[(2+7)\times2^{3}]\]
amistre64
  • amistre64
thatll do 10 yes
ILUVSOCCER
  • ILUVSOCCER
Okay, almost done.

What about 30b?
amistre64
  • amistre64
30b is simple 2 set of paranthesis is required. whats your best effort?
ILUVSOCCER
  • ILUVSOCCER
Okay, let me give it a shot. Wait... 2 sets of parentheses? Can you even do that in a math problem?
amistre64
  • amistre64
you can have 20 sets if need be ...
ILUVSOCCER
  • ILUVSOCCER
30b \[(159-81)\div(3^{3}+12)\]
ILUVSOCCER
  • ILUVSOCCER
Okay, Let me try the other 2. :)
