A.[(1/2)^4 × 2^5 ] : 2^1= B.(-2 ⅓)³= C.(1⅓)² × (1⅓)³= D.Nilai n yang yaitu (1½)^n =5 1/16 E ((¾)²)³×(¾)^5 :¾= tolong jawab pake cara nya pliss

nomor 1 jawabannya ini kayknya
maaf kalau salah wkwk

A.[(1/2)^4 × 2^5 ] : 2^1
= 2^(-4 + 5 ) : 2
= 2^(1-1)
= 2^0
= 1

B.(-2 ⅓)³
= (-7/3)³
= (-7/3) x (-7/3) x (-7/3)
= -343/27
= -12 19/27

C.(1⅓)² × (1⅓)³
= (1⅓)^(2+3)
= (1⅓)^5
= (4/3)^5
= 1.024/243
= 4 52/243

D.Nilai n yang yaitu (1½)^n =5 1/16
(3/2)ⁿ = 81/16
(3/2)ⁿ = (3/2)⁴
n = 4

E ((¾)²)³×(¾)^5 :¾
= ¾^(2x3 + 5 -1)
= ¾^ (6+5-1)
= ¾^10
= 59.049 / 1.048.576
