f(x) = 3x × x × 3x
f(5!) =.......

( - )​

Answer 1

f(x) = 3x(x)(3x)
f(x) = 9x³
_______________
f(5!) = 9(5!)³
f(5!) = 9(5×4×3×2)³
f(5!) = 9(20×6)³
f(5!) = 9(12×10)³
f(5!) = 9×12³×10³
f(5!) = 9×1.728×1.000
f(5!) = 15.552×1.000
f(5!) = 15.552.000

Answer 2

f(x) = 3x × x × 3x

f(5!) = 3(5!) × 5! × 3(5!)

f(5!) = 3( 5 × 4 × 3× 2 × 1 ) × 5! × 3(5!)

f(5!) = 3( 20 × 3 × 2 × 1 ) × 5! × 3(5!)

f(5!) = 3( 60 × 2 × 1 ) × 5! × 3(5!)

f(5!) = 3( 120 × 1 ) × 5! × 3(5!)

f(5!) = 3(120) × 5! × 3(5!)

f(5!) = ( 3 × 120 ) × 5! × 3(5!)

f(5!) = 360 × 5! + 3(5!)

f(5!) = 360 × 120 × 360

f(5!) = 43.200 × 360

f(5!) = 15.552.000
