a. 1/2 (63 – 42)
= 1/2 ((6 x 6 x 6) – (4 x 4))
= 1/2 (216 – 16)
= 1/2 (200)
= 100
b. 8 + 3 x (–3)4
= 8 + 3 x ((–3) x (–3) x (–3))
= 8 + 3 x 81
= 8 + 243
= 251
c. (64 – 44)
= ((6 x 6 x 6 x 6) – (4 x 4 x 4 x 4))
= 1.296 – 256
= 1.040
= 1/2 ((6 x 6 x 6) – (4 x 4))
= 1/2 (216 – 16)
= 1/2 (200)
= 100
b. 8 + 3 x (–3)4
= 8 + 3 x ((–3) x (–3) x (–3))
= 8 + 3 x 81
= 8 + 243
= 251
c. (64 – 44)
= ((6 x 6 x 6 x 6) – (4 x 4 x 4 x 4))
= 1.296 – 256
= 1.040
