y = 56
z = 3

Tentukan,
a × z + x² = ....
zz - y × a = .....​

Answer 1

Verified answer

Soal pertama

a × z + x²

= (25 × 3) + 80²

= (25 × 3) + (80 × 80)

= 75 + 6.400

= 6.475

Soal kedua

zz - y × a

= 3(3) - (56 × 25)

= 9 - 1.400

= -1.391

Answer 2

Penjelasan dengan langkah-langkah:

a = 25

x = 80

y = 56

z = 3

Tentukan,

zz - y × a = ...

jawab

1. a × z + x²

25 × 3 + 80²

= 25 × 3 + (80 × 80)

= 25 × 3 + 6.400

= 75 + 6.400

= 6.475

2. zz - y × a

= 3(3) - 56 × 25

= (3 × 3) - 56 × 25

= 9 - 1.400

= -1.391
