    from math import exp,factorial

def thnks_for_the_fish(machine, cost):
    return sum((exp(-machine) * machine**k) / factorial(k) * (cost + 40 * k**2) for k in range(20))

A,B = map(float,input().split(" "))

print(round(thnks_for_the_fish(A, 160), 3))
print(round(thnks_for_the_fish(B, 128), 3))

    In R could be:

    stdin <- file('stdin')
open(stdin)

line <- as.numeric(strsplit(trimws(readLines(stdin, n = 1, warn = FALSE), which = "right"), " ")[[1]])
cat(format(round(160 + 40*(line[1]+line[1]^2),3), nsmall=3), fill=TRUE)
cat(format(round(128 + 40*(line[2]+line[2]^2),3), nsmall=3), fill=TRUE)

    X,Y=map(float,input().split())
print(round(160+(40*(X+X**2)),3))
print(round(128+(40*(Y+Y**2)),3))

    print(160 + 40*(0.88+0.88**2))
print(128 + 40*(1.55+1.55**2))

    JS

       let value = input.split(" ");
    let ca = 160 + (40 * (Math.pow(parseFloat(value[0]), 2) + parseFloat(value[0])));
    let cb = 128 + (40 * (Math.pow(parseFloat(value[1]), 2) + parseFloat(value[1])));
    console.log(ca.toFixed(3), "\n" , cb.toFixed(3));
