Q. ( 10/10 )

Penjelasan dengan langkah-langkah:

a = √900 = √30² = 30

b = f(2) = 2(2) + 2 = 4 + 2 = 6

c = 2

1.)

= a × b – c²

= 30 × 6 – 2²

= 180 – 4

= 176

2.)

= a + c – b²

= 30 + 2 – 6²

= 32 – 36

= -4

a = √900

b = f(2) = 2x + 2

c = 2

1. a × b – c²

= √900 × (2(2) + 2) – 2²

= 30 × (4 + 2) – 4

= 30 × 6 – 4

= 180 – 4

= 176

2. a + c – b²

= √900 + 2 – (2(2) + 2)²

= 30 + 2 – (4 + 2)²

= 30 + 2 – 6²

= 30 + 2 – 36

= 32 + 36

= –4
