Answer 1

Răspuns:

a=(2,31)^13

b=(2,31)^5

c=(2,31)^63

s a folosit

a^m*a^n=a^(m+n)

a^m:a^n=a^(m-n)

(a^m)^n=a^(m*n )

Answer 2

in primul rand, sa recapitulam formulele:

aᵐ × aⁿ = a ᵐ+ⁿ

aᵐ ÷ aⁿ = a ᵐ-ⁿ

(aᵐ) ⁿ = aᵐ×ⁿ

asadar:

a= (2,31)⁴ × (2,31)^9 = (2,31)^4+9 = (2,31)^13

c= (2,31)^23 ÷ (2,31)^18 = (2,31)^21-18 = (2,31)^5

b= [ (2,31)^7 ]^9 = (2,31)^7×9 = (2,31)^63
