Question

calcule: a) (-3)⁴ b) -3⁴ c) -5³ d) (-5)³ e) (-1,4)² f) -1,4²

Answer 1

a)
= (-3)⁴ = (-3).(-3) . (-3) . ( - 3) = 9.9 = 81
***********************************
b)
= -3⁴ = - 3.3.3.3 = - 9.9 = - 81

***********************************
c)
= -5³  = - 5.5.5 = - 25.5 = - 125

d)

= (-5)³ = (-5).(-5).(-5) = 25.(-5) = - 125

**********************
e)

= (-1,4)²  = ( - 1,4). (- 1,4) = 1,96

*******************

f)
= -1,4² = - 1,4 . 1,4 = - 1,96
