E = 72
N = 90²
S = N + 1
I = 10 : 2
Maka :
P + E + N + S + I = ??
P = f(2) = 2x + 2x
Jawab:
—
P + E + N + S + I
f(2) = 2x + 2x + 72 + 90² + 90² + 1 + 10 ÷ 2
f(2) = 2(2) + 2(2) + 72 + 90² + 90² + 1 + 10 ÷ 2
f(2) = 4 + 4 + 72 + 90² + 90² + 1 + 10 ÷ 2
f(2) = 4 + 4 + 72 + (90 × 90) + 90² + 1 + 10 ÷ 2
f(2) = 4 + 4 + 72 + 8.100 + 90² + 1 + 10 ÷ 2
f(2) = 4 + 4 + 72 + 8.100 + (90 × 90) + 1 + 10 ÷ 2
f(2) = 4 + 4 + 72 + 8.100 + 8.100 + 1 + 10 ÷ 2
f(2) = 4 + 4 + 72 + 8.100 + 8.100 + 1 + 5
f(2) = 8 + 72 + 8.100 + 8.100 + 1 + 5
f(2) = 80 + 8.100 + 8.100 + 1 + 5
f(2) = 8.180 + 8.100 + 1 + 5
f(2) = 16.280 + 1 + 5
f(2) = 16.281 + 5
f(2) = 16.286

P = f(2) = 2x + 2x = 2(2) + 2(2) = 4 + 4 = 8
E = 72
N = 90² = (90 × 90) = 8.100
S = N + 1 = 90² + 1 = (90 × 90) + 1 = 8.100 + 1 = 8.101
