Question

obliczcie nie musi byc dlugo moze byc w pamieci:

a) 5^7 * (-5)^3

b)(-3)^6 * 3^4

c)11^5 / (-11)^3

d)(-7)^8 : 7^5

e) a^9 * (-a)^5

f)(-x)^10 / (-x)^6

Answer 1

a) 5^7 * (-5)^3 = 5^7 * (-1)^3 * 5^3 = (-1) * 5^(7 + 3) = (-1) * 5^10 = - 9 765 625

b)(-3)^6 * 3^4 = (-1)^6 * 3^6 * 3^4 = 1 * 3^10 = 59 0 49

c)11^5 / (-11)^3 = 11^5 : [(-1)^3 * 11^3] = 11^(5 - 3) : (-1) = - 11^2 = -121

d)(-7)^8 : 7^5 = 7^(8 - 5) = 7^3 = 343

e) a^9 * (-a)^5 = - a^(9 + 5) = - a^14

f)(-x)^10 / (-x)^6 = x^(10 - 6) = x^4
