Step-by-step explanation:

3 \sqrt{75}  + 4 \sqrt{27}  - 7 \sqrt{45}

 = 3 \sqrt{3 \times 5 \times 5}  + 4 \sqrt{3 \times 3 \times 3}  - 7 \sqrt{3 \times 3 \times 5}

 = 3 \times 5 \sqrt{3}  + 4 \times 3 \sqrt{3}  - 7 \times 3 \sqrt{5}

 = 15 \sqrt{3}  + 12 \sqrt{3}  - 21 \sqrt{5}

 = 27 \sqrt{3}  - 21 \sqrt{5}

 = 3(9 \sqrt{3}  - 7 \sqrt{5} )
