Simplify the following rational expression
MatroZZZ [7]

Answer:

The value of k for the expression to be undefined is 9 .

Step-by-step explanation:

Given as :

The rational expression is written in the form

\dfrac{5k^{2}-50k+45}{k^{2}-18k+81}

Now, according to question

The expression to be undefined , denominator should be 0

<u>As, \frac{1}{0} is infinite ( ∞ ) term and it is undefined  , so for expression to be undefined , the denominator should be 0</u>

∴ k² - 18 k + 81 = 0

Or, k² - 9 k - 9 k + 81 = 0

Or, k ( k - 9 ) - 9 ( k - 9) = 0

Or, ( k - 9 ) ( k - 9 ) = 0

Or,  ( k - 9 ) = 0  ,   ( k - 9 ) = 0

∴  k = 9

So, The value of k = 9

Hence The value of k for the expression to be undefined is 9 . Answer

a) <u>n² + 6 </u>

~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.

  • If n = 1, first term = 1² + 6 = 7
  • n = 2, second term = 10
  • n = 3, third temm = 15
  • n = 4, fourth term = 22
  • n = 10, tenth term = 106

b) <u>3n²</u>

  • If n = 1, first term = 3
  • n = 2, second term = 12
  • n = 3, third term = 27
  • n = 4, fourth term = 48
  • n = 10, tenth term = 300
