Chapter 1, Problem 1SAP

To determine

To select: the expression of prime factorization of 54 from the given options.

Answer to Problem 1SAP

  $9\times 6$

Explanation of Solution

Given information:

Number to be factorized = 54

The given options are as follows:

  A. $9\times 6$

  B. $3\times 3\times 6$

  C. $3\times 3\times 2$

  D. $3\times 3\times 3\times 2$

  E. $5.4\times 10$

Calculation:

The prime factorization of 54 is as follows:

  $\begin{array}{c}\text{Prime factor of 54}=3\times 3\times 3\times 2\\ =\left(3\times 3\right)\times \left(3\times 2\right)\\ =9\times 6\end{array}$

Thus, option A. is correct.
