Simplify
(p^-4+m p^2m)^-4
----------------
(p^-4)^-m
Theses are the choices
A) p-16m + 16 I say its A or B
B) p-8m – 4
C) p-11m – 4
D) p-3m + 16
after the p there is suppose to be a ^ for the power to sign...
OK, the numerator is
(p^(-4+3m))^-4 or p^(16-12m)
and the denominator is
p^4m
so the fraction becomes...
p^(16-16m) which is A
check my work.
this problem has been posted about 3 times in the last couple of days.
due to a lack of brackets, it was always too confusing to determine the order of operations.
Looking at your answers, I can finally conclude you meant
(p-4+m p2m)-4 / (p-4)-m
= (p-4+3m)-4 / p4m
= p16-12m / p4m
= p16-16m
which is A
Where did you get 3m from? The problem reads
Simplify
(p^-4+m p^2m)^-4
----------------
(p^-4)^-m
Theses are the choices
A) p-16m + 16
B) p-8m – 4
C) p-11m – 4
D) p-3m + 16
I say its A or B
bobpursley and I both got the 3m by correctly using the rules for exponents.
Ok but the answer is typed incorectly choice A is
p^-16+16 not
= p^16-16m
Kim!
Come on!!!!
-16 + 16m vs 16m - 16 ??????
Is it the same thing? I don't know, but my first choice was A. I still do not understand how
(p-4+m p2m)-4 / (p-4)-m
= (p-4+3m)-4 / p4m
= p^16-12m / p^4m
where does the 12 fit in? and how does the answer end up as A?
= p16-16m
we used three basic rules
1. (ax)(ay) = ax+y
2. (ax)/(ay) = ax-y
3. (ax)y = axy
to attempt questions such as the one above without knowing those rules would be futile.
