=== Assistant: You’re right—if the exponent is the whole −5+7-5+7−5+7, then ===
You’re right—if the exponent is the whole (−5+7)(-5+7)(−5+7), then

(−5+9)−5+7=4 2=16=24.(-5+9)^{-5+7}=4^{\,2}=16=2^{4}.(−5+9)−5+7=42=16=24.
So, when read as single stacked fractions,

πr224(−5+9)−5+7 πr2=πr22424πr2=1(r≠0).\frac{\pi r^{2}2^{4}}{(-5+9)^{-5+7}\,\pi r^{2}}
=\frac{\pi r^{2}2^{4}}{2^{4}\pi r^{2}}
=1\qquad (r\neq 0).(−5+9)−5+7πr2πr224=24πr2πr224=1(r=0).
The only time it wouldn’t be 111 is if the linear slash makes the trailing πr2\pi r^{2}πr2 sit outside the denominator, i.e.

πr224/(−5+9)−5+7 πr2=(πr22424)πr2=π2r4.\pi r^{2}2^{4}/(-5+9)^{-5+7}\,\pi r^{2}
=\Big(\frac{\pi r^{2}2^{4}}{2^{4}}\Big)\pi r^{2}
=\pi^{2}r^{4}.πr224/(−5+9)−5+7πr2=(24πr224)πr2=π2r4.
So the math agrees with you; the discrepancy is purely about parsing. Write it as a stacked fraction or with parentheses to lock in the meaning.
