i got an answer of -3/2
Let's see your working. Using Draw if possible please :D
Or in text if you prefer
the top part gave me -18 and the bottom gave me 12. so it looked like -18/12, which gave me -3/2
What does a negative exponent mean?
does 3^-2 mean, -3*-3 or 3*-3?
A negative exponent works like this:|dw:1327954914818:dw|
i thought i was only supposed to do that when there was a x or something. i thought for regular numbers i was just supposed to keep going
Nope, it should work equally well for regular numbers,
ok, so i got an answer of 1/27 this time
want me to show you how?
Here's why it works for regular numbers:|dw:1327955027052:dw|
But it's 2/9 DIVIDED BY 1/12, not multiplied :D
If you go to the top, it was a fraction as you wrote it out for me, remember :D
Chill, easy mistake to make :D
So what's the right answer then :) ?
i flipped it so it became (2/9)(12/1)
No problem :D
Yep , that's how I'd do it too!
