b) 10⁻³:10³=

c) 2⁻¹:10³=

d)7¹¹•2⁻³=

e)x³•x⁻⁷•x⁶=​

Answer 1

Resposta:

Explicação passo-a-passo:

a) x = (2⁰+ 2⁻¹): (2⁰- 2⁻¹)=

x = (1 + 1/2) : (1 - 1/2)

x = [(2+1)/2] : [(2-1)/2]

x = 3/2 : 1/2

x = 3/2 . 2/1

x = 6/2

x = 3

b) 10⁻³:10³=

10^(-3-3)

10^(-6)

c) 2⁻¹:10³=

= 1/2 . 1/1000

= 1/2000

d)7¹¹•2⁻³=

7^11 . 1/8

7^11 / 8

7^5= 16807

7^6 = 117649

= 7^6.7^5 /8

= 117649 . 16807 / 8

= 1977326743/8

e)x³•x⁻⁷•x⁶=​

= x^(3-7+6)

= x^(-4+6)

= x^2
