Answer:
![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
Step-by-step explanation:
Using the rules of exponents
×
=
,
=
,
= ![a^{mn}](https://tex.z-dn.net/?f=a%5E%7Bmn%7D)
Simplifying the product of the first 2 terms
× ![\frac{a^{q^2+qr} }{a^{qr+r^2} }](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5E%7Bq%5E2%2Bqr%7D%20%7D%7Ba%5E%7Bqr%2Br%5E2%7D%20%7D)
=
× ![a^{q^2-r^2}](https://tex.z-dn.net/?f=a%5E%7Bq%5E2-r%5E2%7D)
= ![a^{p^2-r^2}](https://tex.z-dn.net/?f=a%5E%7Bp%5E2-r%5E2%7D)
Simplifying the third term
5(![(a^p+r)^{p-r}](https://tex.z-dn.net/?f=%28a%5Ep%2Br%29%5E%7Bp-r%7D)
= 5
= 5![a^{(p^2-r^2)}](https://tex.z-dn.net/?f=a%5E%7B%28p%5E2-r%5E2%29%7D)
Performing the division, that is
← cancel
on numerator/ denominator leaves
= ![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
Answer:
21
Step-by-step explanation:
-(-26) would be positive 26 because one negative multiplied by another negative equals a positive. We are left with -5+26 which would equal 21.
