Question

Factorize 163x^ - 2/81x^4

Answer 1

Answer:

 $\frac{163x^{-2} }{81x^{4} }$ $= \frac{163}{81x^{6} }$

Step-by-step explanation:

Given : $\frac{163x^{-2} }{81x^{4} }$

To find : Factors of the above expression

Solution :

• The given expression is  $\frac{163x^{-2} }{81x^{4} }$
• In order to factorize this expression, we have to cancel out common factors.
• Here, $163$ is a prime number.
• $81$ is a composite number.
• ∴ $\frac{163x^{-2} }{81x^{4} }$ $= \frac{163x^{-2}*x^{2} }{81x^{4} *x^{2} }$

           $= \frac{163}{81x^{6} }$
