2 3/8 * 5 3/4 = 437/32 or 13 21/32

2 3/8 * 5 3/4 = 19/8 × 23/4

= (19 × 23) / (8 × 4)

= 437/32

= 13 21/32

2 3/8 * 5 3/4 = 19/8 × 23/4

= (19 × 23) / (8 × 4)

= 437/32

= 13 21/32

When a = 2, b = 3, and c = 4,

3(a + b + c)^2 = 3(2 + 3 + 4)^2 = 3(9^2) = 3(81) = 243

3(a + b + c)^2 = 3(2 + 3 + 4)^2 = 3(9^2) = 3(81) = 243
