Respuesta :

change -3 and 3/8 into -27/8, which is the cube of -3/2
change 5 and 4/9 into 49/9, which is the square of 7/3
In case you didn't know how to change, the whole multiple the bottom, and plus the top, ignore the positive/negative sign: 3*8=24, 24+3=27, and 5*9=45, 45+4=49
5 4/9  = 49 /4  = square of 7/2

5 4/9  = (3 1/2)^2

- 3 3/8  = -27/8  = (-3/2)^3  or (-1 1/2)^3
