tolong dijawab no. 2 dan no.3

3. a) y³ * 2y7 * (3y)²
= y³ * 2y7 * 3² y²
= y¹² * 18
= 18 y¹²

Maaf yg tadi salah ✌

b) b * 2y7 * b³ * y ²
= 2 b⁴ y9
c) 3m³ x (MN) ⁴
= 3 m³ * m⁴ * n⁴
= 3 m7 * n4
d) (tn³)⁴ * 4 t³
= t1 * n12 * 4t3
=4 n12 t7

e) (2x³) * 3 (x²y²)³ * 5 y⁴
= 2x3 * 3x6y6 * 5 y4
= 2 x9 * 3y10 * 5
= 30 * x9 * y10
