Chapter 4, Problem 12CR

To determine

To factor the monomial $15r^2{s}^2$

Answer to Problem 12CR

  $3\times 5\times r\times r\times s\times s$

Explanation of Solution

Given information:

Expression $15r^2{s}^2$

Calculation:

To factor an expression, simply break it down into its smallest constituents. So, here,

15 may be written as $3\times 5$

  $r^2$ may be written as $r\times r$

  $s^2$ may be written as $s\times s$

So the entire monomial will be written as-

  $15r^2{s}^2=3\times 5\times r\times r\times s\times s$

Conclusion-

  $3\times 5\times r\times r\times s\times s$
