Given:–
•Value of m = 3 and n=2.
To Find:–
[tex] \: \sf(1)9 {m}^{2} – 10 {n}^{3} \\ \\ \sf (2)2 {m}^{2} {n}^{2} \\ \\ \sf (3)5 {m}^{2} n[/tex]
Solution:–
we have,
[tex] \: \: \sf(1)9 {m}^{2} – 10 {n}^{3} \\ \\ \: \: \sf \: = 9 \times {3}^{2} – 10 \times {2}^{3} \\ \\ \: \: \sf \: = 9 \times9 – 10 \times 8 \\ \\ \: \: \sf \: = 81 – 80 = 1 [/tex]
[tex] \: \: \sf \: (2)2 {m}^{2} {n}^{2} \\ \\ \: \: \sf \: = 2 \times {3}^{2} \times {2}^{2} \\ \\ \: \: \sf \: = 2 \times 9 \times 4 \\ \\ \: \: \sf \: = 72[/tex]
[tex] \: \: \sf \: (3)5 {m}^{2} n \\ \\ \: \: \sf \: = 5 \times {3}^{2} \times 2 \\ \\ \: \: \sf \: = 5 \times 9 \times 4 \\ \\ \: \: \sf = 180[/tex]
