Hello, PhilC!
. Right!
. ??
. Neither do I
. not quite
I'm really struggling with this one. I know the answer (it's in the back of the book) but I can't see how they get to the answer at all.
<sorry, the display is wrong, the '2' '3' and '4''s are supposed to be powers>
Simplify:
a2b * ac2 / b2c
2c 2b 2a
This obviously equals:
a2b * ac2 *2a
2c 2b b2c
The answer in the book is:
b3
ac
and I don't get how the 'a' got to the bottom of this.
My answer always ends up something like:
a4
b2
Thanks, I did say "always ends up something like" and your answer is one of the ways it usually ends up.
I thought I was going mad. I've double checked that I'm looking at the correct question / answer etc many times (if i have double checked many times at least I know it has to be an even number of times).
Finally I can move onto the next section of the book.
Thanks again!
