Q. ( +10 )


• f(x) = x!!!! + x² - x
• f(10) = . . .

​

Answer 1

f(x) = x!!!! + x² - x

f(10) = 10!!!! + 10² - 10

f(10) = (10 × 6 × 2) + (10 × 10) - 10

f(10) = (60 × 2) + 100 - 10

f(10) = 120 + 100 - 10

f(10) = 220 - 10

f(10) = 210

Answer 2

10!!!!

= 10 × 6 × 2 × 1

= 60 × 2 × 1

= 120 × 1

= 120

• f(x) = x!!!! + x² - x

• f(10) = 10!!!! + 10² - 10

• f(10) = 120 + ( 10 × 10 ) - 10

• f(10) = 120 + 100 - 10

• f(10) = 220 - 10

• f(10) = 210
