## anonymous one year ago (3s/2t)-2 -How do you simplify this?

1. anonymous

I dont think you can simplify that much. But you can write it as: $0.5(3s*y-4)$

2. anonymous

I dont think that is right. I got this problem from a law of exponent sheet

3. welshfella

is it (3s/2t)^(-2) ?

4. anonymous

$\left( \frac{ 3s }{ 2t } \right)^{-2}=\frac{ 1 }{ \left( \frac{ 3s }{ 2t } \right)^2 }=\left( \frac{ 2t }{ 3s } \right)^2=?$

5. welshfella

-2 being the exponent

|dw:1442761607148:dw| thats how it looks
