Q.9² – 5² ÷ 2² + 4(a)a = 4nt:mengingat usnm dulu :)
Penjelasan dengan langkah-langkah:
9² – 5² ÷ 2² + 4(a)
a ➝ 4
——
9² – 5² ÷ 2² + 4(4)
= (9.9) – 5² ÷ 2² + 4(4)
= 81 – (5.5) ÷ 2² + 4(4)
= 81 – 25 ÷ 2² + 4(4)
= 81 – 25 ÷ (2.2) + 4(4)
= 81 – 25 ÷ 4 + (4.4)
= 81 – 25 ÷ 4 + 16
= 81 – 6,25 + 16
= 74,75 + 16
= 90,75
