Answer:
[tex]13\times 9[/tex]
Step-by-step explanation:
We are given that 54+63
We have to find the sum as the product of relatively prime numbers
In order to find the numbers we will find first sum and then factor
Sum=54+63=117
Factors of 117 are 13 and 9
[tex]117=13\times 9[/tex]
13 and 9 are relatively prime because the gcd of 13 and 9 is 1.
Hence, [tex]54+63=13\times 9[/tex]
