i,(76.34-19.64):(38.9)

k,(2+4+6+...+100).(36.333-108.111)

m,(5.4^11-3.16^5):4^10

n,7256.4375-725

______________

3650+4375.7255

Answer 1

a: \(=347\cdot4\cdot9\cdot400:8=347\cdot36\cdot50=624600\)

c: \(=16:\left\{400:\left[200-37-138\right]\right\}\)

\(=16:\left\{400:25\right\}=16:16=1\)

e: \(=46-\left[300:15\right]-2=46-20-2=24\)
