If ( I _ m = ₁^ e ( x )^ m dx ), where ( m N ), then (I₁₀+10 I₉ ) is equal to -
Options
- A( e ¹⁰ )
- B( e ¹⁰ 10 )
- C( e )
- D( e -1 )
Correct answer
C. ( e )
Step-by-step solution
( aligned & I ₁₀= ₁^ e 1 ( x )¹⁰ dx = [( x )¹⁰ x ]₁^ e & - ₁^ e 10( x )^9 1 x xdx = e -0-10 ₁^ e ( x )^9 dx & = e -10 I ₉+10 I ₉= e aligned )
