Question

doar punctul d va rog ​

Answer 1

Răspuns:

Explicație pas cu pas:

d)

x=[2^(12+18)+5^(70-10)-3^(25x2)):[2^(4+3+23)+5^(15×4)-3^(2x25)]=

=(2^30+5^60-3^50):(2^30+5^60-3^50)=1

x=1

Answer 2

Răspuns:

Explicație pas cu pas:

d) x=[2^12×2^18+5^70÷5^10-(3^25)^2]:[4^2×2^3×2^23+(5^15)^2^2-(3^2)^5^2]

=[2^30+5^60-3^50]:[(2^2)^2×2^3×2^23+(5^15)^4-(3^2)^25]

=[2^30+5^60-3^50]:[2^4×2^3×2^23+5^60-3^50]

=[2^30+5^60-3^50]:[2^7×2^23+5^60-3^50]

=[2^30+5^60-3^50]:[2^30+5^60-3^50]

=(2^30:2^30)+(5^60:5^60)-(3^50:3^50)

=1+1-1=2-1=1

=> x=1
