Question

Determine o valor das expressões
a-)(-5)^3×5^2
b)1^2×2^2×3^0×5^1
c)(-4)^6
d)2^-3×8^2
h) 1^18+99^0

Answer 1

a)(-5)^3x5^2= (-5)x(-5)x(-5)x5x5= 25x(-5)x25= (-125)x25= −3125

b)1^2x2^2x3^0x5^1= 1x1x2x2x1x5= 1x4x5= 20

c)(-4)^6=(-4)x(-4)x(-4)x(-4)x(-4)x(-4)= 4096

d)2^-3x8^2= (1/2)^3 x8^2=1/8 x64= 64/8 (:8)= 8/1 ou 8

h) 1^18+99^0= 1+1=2
