OK, rosala.....

Remember that we can multiply in any order that we'd like......so, for instance, 3*4*5 = 5*3*4

So look at this........ 3*w5*7*w5   is really just the same thing as 3*7 *w5 * w5

So we have 21*w5*w5     ....   and remember by a property of exponents (or powers) that an * an = an+n

Therefore, w5 * w5  =  w5+5 = w10

And putting this all together, we get ...... 21w10

Does that make sense??

so well solve it like this :

3w57w5

for this well use this rule to solve it axbx=(ab)x

so well do this like this 

=(3w7w)5   (we multiply both the values )

=21w5   ANSWER !   and Pumpkinguy u shouldnt have said like that to KOOL-AID !i hope this helps u !

and who ticked zegroes answer ! i dont think it is correct ! was it u Cphill or melody !

Gotta be careful here, rosala.....

(3w * 7w)5  = (21w2)5 = (21)5 * w10 = 4,084,101w10......this is incorrect.....

We have to use this rule here ....   an * am  =  am+n

So we have

3w5 * 7w5  = 3*7*w5* w5 = 21w10

And that's the correct answer
