8dasawarsa+8lustrum-5windu=...... dasawarsa . Pake cara ya

8dasawarsa + 8lustrum-5 windu= 8 dasawarsa
8lusrum=40 thn =4 dasawarsa
5 windu=40thn =4dasawarsa
8+4-4=8dasawarsa

1 dasawarsa = 10 th : 8×10 = 80 th
1 lustrum = 5 th : 8×5 = 40 th
1 windu = 8 th : 5×8 = 40 th
80 th + 40 th + 40 th = 160 th ÷ 10 th
= 16 th

maaf klo salah
