topjm [15]2 years ago
6 0

Answer:

The answer is option 3.

Step-by-step explanation:

The steps are :

3 \sqrt{2} (5 \sqrt{6}  - 7 \sqrt{3})

= (3 \sqrt{2} )(5 \sqrt{6} ) - (3 \sqrt{2} )(7 \sqrt{3} )

= 15 \sqrt{12}  - 21 \sqrt{6}

= 15 \sqrt{4 \times 3}  - 21 \sqrt{6}

= 15(2) \sqrt{3}  - 21 \sqrt{6}

= 30 \sqrt{3}   - 21  \sqrt{6}
