Answer:
1) [tex]20 \sqrt{2} [/tex]
2) [tex]64[/tex]
3) [tex]45 \sqrt{3} [/tex]
Step-by-step explanation:
1) [tex]5 \sqrt{32} [/tex]
[tex]5 \times {2}^{2} \sqrt{2} [/tex]
[tex]5 \times 4 \sqrt{2} [/tex]
[tex] = 20 \sqrt{2} [/tex]

2) [tex]4 \sqrt{256} [/tex]
[tex] \sqrt{256} = {16}^{2} = 16[/tex]
[tex]4 \times 16 = 64[/tex]

3) [tex]5 \sqrt{ = 243} [/tex]
[tex]5 \times {3}^{2} \sqrt{3} [/tex]
[tex]5 \times 9 \sqrt{3} [/tex]
[tex]45 \sqrt{3} [/tex]
