Step-by-Step Solution

To solve this problem, follow these steps:

Step 1: Simplify the first fraction:

The first expression is 35xy77xy\frac{35x \cdot y^7}{7xy}.

  • Cancel the common factor of 77: 35÷7=535 \div 7 = 5.

  • This simplifies to 5xy7xy\frac{5x \cdot y^7}{x \cdot y}.

  • Cancel the common factor of xx: x/xx/x cancels to 11.

  • Cancel part of the yy terms: y7/y=y71=y6y^7/y = y^{7-1} = y^6.

  • The result is 5y65y^6.

Step 2: Simplify the second fraction:

The second expression is 8x5y\frac{8x}{5y}.

  • No common factors in the numerator and denominator, so it remains 8x5y \frac{8x}{5y} .

Step 3: Multiply these simplified results:

Now, multiply the results from Step 1 and Step 2: 5y68x5y5y^6 \cdot \frac{8x}{5y}.

  • The factor of 55 in 5y65y^6 and 8x5y\frac{8x}{5y} cancels: 5/5=15/5 = 1.

  • This results in y68xyy^6 \cdot \frac{8x}{y}.

  • Cancel part of the yy terms: y6/y=y61=y5y^6/y = y^{6-1} = y^5.

Thus, the simplified expression is 8xy58xy^5.

Therefore, the solution to the problem is 8xy5 \mathbf{8xy^5} .

Answer

8xy5 8xy^5
