Question

Calcule:
a) (-7)² =
b) -7² =
c) (-3)⁴
d) -3⁴
e) -3³
f) (-5)³

Answer 1

$a) \\ \\ (-7)^2 => (-7)* (-7) => 49$

===
$b) \\ \\ -7^2 = -(7)~2 = - 49$

===
$c) \\ \\ (-3)^4 = (-3)*(-3)*(-3)*(-3) = > 81$

====
$d) \\ \\ - 3^4 => -81$

====
$e) \\ \\ - 3 ^3 => -27$

====
$f) \\ \\ (-5)^3 => (-5)*(-5)*(-5) = > -125$

Answer 2

a)(-7).(-7)=49
b)-7² =-49
c)(-3).(-3).(-3).(-3)=81
d)-3.-3.-3.-3=-81
e)-3.-3.-3=-27
f)(-5).(-5).(-5)=-125
