Diketahui mn³ + 26 = 50 dan 2/3 m = 4/n maka nilai dari 3/2 n + 1/3 m – 1 adalah​

Jawaban:

4

Penjelasan dengan langkah-langkah:

mn³ + 26 =50

mn³ = 24

2/3 m = 4/n

2mn =12

mn =6

n=6/m

subs n =6/m

m(6/n)³ = 24

m(216/m³)=24

216/m² =24

216 = 24m²

m² = 9

m = √9

m = 3

subs m= 3

n = 6/m

n = 6/3

n = 2

3/2 n + 1/3 m – 1

=3(2) / 2 + 3 / 3 -1

= 6 / 2 + 1 – 1

= 3 + 1 – 1

= 3
