Q.
f(x) = 4² + 3³ - x²
f(4) = . . . .
.-.![]()
f(x) = 4² + 3³ - x²
f(4) = . . . .
.-.
Penjelasan dengan langkah-langkah:
f(x) = 4² + 3³ - x²
f(4) = . . . .
f(x) = 4² + 3³ - x²
f(4) = (4×4) + (3×3×3) - 4²
f(4) = 16 + (9×3) - (4×4)
f(4) = 16 + 27 - 16
f(4) = 43 - 16
f(4) = 27
- f(x) = 4² + 3³ - x²
- f(4) = 4² + 3³ - 4²
- f(4) = ( 4 × 4 ) + ( 3 × 3 × 3 ) - ( 4 × 4 )
- f(4) = 16 + 27 - 16
- f(4) = 43 - 16
- f(4) = 27
