Salutare!
a)
7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 7 × 8 = 56
7 · 7 · 7 · 7 · 7 · 7 ·7 · 7 = 7⁸
_______________________
d)
(x + y) + (x + y) + (x + y) + (x + y) = 4 (x + y)
(x + y) • (x + y) • (x + y) • (x + y) = (x + y)⁴
_______________________
b)
24 + 24 + 24 + 24 + 24 + 24 = 24 · 6 = 144
24 · 24 · 24 · 24 · 24 · 24 = 24⁶
_______________________
e)
a + a + a + b + b + b = 3a + 3b = 3(a + b)
a · a · a · b · b · b = a³ · b³
_______________________
c)
a + a + a + a + a + a + a + a + a = 9 · a
n + m + m + n + n + m = 3n + 3m = 3 (n + m)
_______________________
f)
a · a · a · a · a · a · a · a · a = a⁹
n · m · m · n · n · m = n³ · m³
