Question

3X (5/4-3/8)²=

(4/3-1/2)² +4=

1/2X(5-7/2)³

Answer 1

3 x (5/4 - 3/8)²=

5/4 - 3/8 = mmc (4,8)=8
10/8 - 3/8 = 7/8

3 x (7/8)² = 3 x 49/64 = 147/64
____________________________
(4/3 - 1/2)² + 4 = ---mmc(2,3) = 6
(8/6 - 3/6)² + 4 = 
 (5/6)² + 4= 25/36 + 4 = 169/36
___________________________________

1/2 x (5-7/2)³ = 
1/2 x (3/2)³ = 1/2 x 27/8 = 27/16
