Question

9!! × x² + y - 1 = ...
x = 2
y = 3
​

Answer 1

SOAL 1

___________________________________________

9!! × x² + y - 1

x → 2

y → 3

___________________________________________

9!! × 2² + 3 - 1

= (9 × 7 × 5 × 3 × 1) × (2 × 2) + 3 - 1

= (63 × 5 × 3 × 1) × (2 × 2) + 3 - 1

= (315 × 3 × 1) × (2 × 2) + 3 - 1

= (945 × 1) × (2 × 2) + 3 - 1

= 945 × 4 + 3 - 1

= 3.780 + 3 - 1

= 3.783 - 1

= 3.782

Answer 2

9!! × x² + y - 1

x = 2

y = 3

------------------------------------------

9!! × 2² + 3 - 1

• = ( 9 × 7 × 5 × 3 × 1 ) × 2² + 3 - 1

• = ( 63 × 5 × 3 × 1 ) × 2² + 3 - 1

• = ( 315 × 3 × 1 ) × 2² + 3 - 1

• = ( 945 × 1 ) × 2² + 3 - 1

• = 945 × 4 + 3 - 1

• = 3.780 + 3 - 1

• = 3.780 + 2

• = 3.782
