Answer:
[tex]\frac{511\,\,\sqrt{3} }{99}[/tex] which is an irrational number
Step-by-step explanation:
Recall that the repeating decimal 0.7373737373... can be written in fraction form as: [tex]\frac{73}{99}[/tex]
Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:
[tex]147=7^2\,3[/tex]
Then, 7 will be able to go outside the root when we compute the final product requested:
[tex]\frac{73}{99} \,*\,7\,\sqrt{3} =\frac{511\,\,\sqrt{3} }{99}[/tex]
This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number [tex]\sqrt{3}[/tex]
