Find the answer to zero point 73 repeating times square root of 147 end square root and select the correct answer below. Also, i
liubo4ka [24]

Answer:

\frac{511\,\,\sqrt{3} }{99}  which is an irrational number

Step-by-step explanation:

Recall that the repeating decimal 0.7373737373... can be written in fraction form as: \frac{73}{99}

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:

147=7^2\,3

Then, 7 will be able to go outside the root when we compute the final product requested:

\frac{73}{99} \,*\,7\,\sqrt{3} =\frac{511\,\,\sqrt{3} }{99}

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 \sqrt{3}
