Question

calcule: a)5^3 b)(-5)^3 c)5^-3 d)(-2/3) e)(1/50)^-2 f)(-11/7)^0 g)(3/2)^1 h)(-1/2)^0 i)-(-2)^5 j)-10^2 k)10^-3 l)-(-1/2)^-2

Answer 1

a
5³= 5 * 5 * 5  = 125
b
(-5)³ = - 125
c
5⁻³  = ( 1/5)³  = 1/125
d
incompleto
e
( 1/50)⁻² = ( 50/1)² = 2500
f
( - 11/7)⁰ = 1 ****
g
( 3/2)¹ = 3/2
h
( - 1/2)⁰ = 1 ***
i
- ( -2)⁵ =   - ( -32) = 32 
J
- 10² = - (10 ) ( 10)  = -100 ****
K
( 10)⁻³  = ( 1/10)³ = 1/1000
L
- ( -1/2)⁻²  =  - (2/1)² = -4

Answer 2

Boa tarde!

a) 5³= 125
b) (-5)³= -125
c) 5  -³= 1/125
d) (-2/3)³= -8/27
e) 1/50 -²=  50²=  2500
f) (-11/7)^0= 1
g) (3/2)¹ = 3/2
h) (-1/2)^0= 1
i) - (-2)^5= -(- 32)= 32
j) - 10²= -100
k) 10 -³ = (1/10)³= 1/1000
i) - (-1/2)-² = - (-2)²= - (+4)= -4
