Simplify:
4s raised to the negative 2 power  (4t)raised to the 2 power

4s^2  (4t)^2
what about it?
Are we factoring?
If so, I see the difference of squares
= 4(s+t^1)(st^1)
or
= 4(s+1/t)(s1/t)

No the question only says to simplify and the problem was 4s^2(4t)^2

sorry, did not see that first 2
ok, factoring is simplifying
or you could so this
4/s^2  1/(16t^2)
= (64t^2  s^2)/(16s^2t^2)
= (8t+s)(8ts)/(16s^2t^2)
my revised solution for the above:
4s^2  16t^2
= 4(s^1 + 2t^1)(s^1  2t^1)
or
= 4(1/s + 2/t)(1/s  2/t)
