OpenStudy (anonymous):

are the answers filled in right...my teacher said the last 2 are incorrect @UnkleRhaukus

OpenStudy (anonymous):

but the first one is correct

OpenStudy (unklerhaukus):

6/3/2 LtR (6/3)/2 =2/2 =1 RtL 6/(3/2) =(2*6)/3 = 12/4 =

OpenStudy (anonymous):

how did you know to do 2*6?

OpenStudy (unklerhaukus):

2 times 6

OpenStudy (unklerhaukus):

\[\frac a{b/c}=\frac{ca}{b}\]

OpenStudy (anonymous):

ohh would it be the same for the third?

OpenStudy (anonymous):

so number 2 should be 3 or 4?

OpenStudy (unklerhaukus):

LtR \[(2^3)^2\] RtL \[2^{(3^2)}\]

OpenStudy (anonymous):

for the second one is it 512?

OpenStudy (anonymous):

RtL 6/(3/2) =(2*6)/3 = 12/4 = is the answer to this 4 or 3 because 12/3=4 and 12/4 is 3

OpenStudy (anonymous):

@UnkleRhaukus

OpenStudy (unklerhaukus):

ops** RtL 6/(3/2) =(2*6)/3 = 12/3 = 4

OpenStudy (unklerhaukus):

LtR (2^3)^2 =8^2 =64 RtL 2^(3^2) =2^9 =512
