Answer:
1
Step-by-step explanation:
multiply and divide(left to right)
=9-9+1
Add and subtract(left to right)
=1
it is non-linear, because to get 8 to 24 takes 16 but 0 to 8 only takes 8 (i'm not good at explaining)
<span>(4 · 2^5) ÷ (2^3 · 1/16 )
</span>= (2^2 · 2^5) ÷ (2^3 · 2^-4 )
= (2^7) ÷ (2^-1)
= 2^8
