x.y = -130
x.(1-x) = -130
x - x² = -130
x² - x = 130
(x - (1/2))² = 130+(1/4)
(x - (1/2))² = 521/4
(x - (1/2)) = √(521/4) atau -√(521/4)
x = (1/2) + √(521/4) atau (1/2) - √(521/4)
2. 13+ (-10) + (-2) = 1
ket: smua angka dipangkatkan nol ( ...°) hasilnya 1, jd 2° = 1.
klo ada jawaban yg lebih benar kasih tahu ya!!!
Ada jwb yg lebih tepat
1). 13+ (-10) + (-1) + (-1) = 1
2). 13x (-10) x (-1) x (-1) = -130 saya yakin itu jawaban yg paling benar.
