help meeee!! bantuin yak yg ngerti pakek caranya lengkap okay :'))

Nomer (1)
a) 4 × 4 × 4 × 4 = 4⁴

b) (-7) × (-7) × (-7) = (-7)³

c) (-y) × (-y) × (-y) × (-y) × (-y) = (-y)⁵

nomer 2)

a) 2⁶ × 2⁷ = 2⁶⁺⁷ = 2¹³

b) (-3)⁵ × (-3) × (-3)⁷ = (-3)⁵ ⁺¹ ⁺⁷ = (-3)¹³

c) 3a² × 3a³ = 9a⁵

d) 9a × a² × b × 3b³ = 9a³ × 3b⁴

e) a⁴ × b³ × c² × d (karena tidak ada variabel (huruf) yang sama maka hasilnya tetap)

3) lebar = 4a; panjang = 12a; tinggi = 8a
LP = 2( (p×l) + (l × t) + (p × t))
Lp = 2 ( (12a × 4a) + (4a × 8a) + (12a × 8a)
LP = 2 (48a² + 32a² + 96a²)
LP = 2 (176a²)
LP = 352 a²
