Question

calcule:
a) (-5)elevado a 4 =
b)(2) elevado a -1 =
(-7)
c)(-7,2)elevado a 2=
d)(5)elevado a -3 =
(6)
e)(-3) elevado a -4 =
(10)

Answer 1

a)(-5)^4 = -5.-5.-5.-5 = 625
b)(2)-¹ = (1/2)¹ = 1/2
c)(-7,2)² = -7,2 . -7,2 = 51,84
d)(5)-³ = (1/5)³ = 1/5 . /1/5 .1/5 = 1/125
e)(-3)^-4 = (-1/3)^4 = -1/3.-1/3.-1/3.-1/3 = 1/81
