Q.9² - 5² ÷ 2² + 4(a)a = 4nt:mengingat usnm dulu :)​

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

sf{{{a → 4}}}

= sf{{{9² - 5² ÷ 2² + 4(a)}}}

= sf{{{9² - 5² ÷ 2² + 4(4)}}}

= sf{{{9² - 5² ÷ 2² + (4+4+4+4)}}}

= sf{{{9² - 5² ÷ 2² + (12+4)}}}

= sf{{{9² - 5² ÷ 2² + 16}}}

= sf{{{9² - 5² ÷ (2+2) + 16}}}

= sf{{{9² - 5² ÷ 4 + 16}}}

= sf{{{9² - (5+5+5+5+5) ÷ 4 + 16}}}

= sf{{{9² - (10+10+5) ÷ 4 + 16}}}

= sf{{{9² - (20+5) ÷ 4 + 16}}}

= sf{{{9² - 25 ÷ 4 + 16}}}

= sf{{{(18+18+18+18+9) - 25 ÷ 4 + 16}}}

= sf{{{(36+36+9) - 25 ÷ 4 + 16}}}

= sf{{{(72+9) - 25 ÷ 4 + 16}}}

= sf{{{81 - 25 ÷ 4 + 16}}}

= sf{{{81 - (25 ÷ 4) + 16}}}

= sf{{{81 - 6,25 + 16}}}

= sf{{{74,75 + 16}}}

= ttpink{{{90,75}}}
