Question

Ai trả lời cho mình sẽ tik cho nhé

(x+1)+(x+2)+(x+3)+...+(x+100)=7450

2x -2^3×3^2=138

(6x-3^4)×7^3=3×74

Answer 1

(x+1)+(x+2)+(x+3)+...+(x+100)=7450

(100x+1+2+3+4+...+100)=7450

100x+5050=7450

100x=7450-5050

100x=2400

x=2400:100

x=24

Answer 2

Còn 2 phần nữa mà bạn

Answer 3

\(2\times x-2^3\times3^2=138\)

\(2\times x-8\times9=138\)

\(2\times x-72=138\)

\(2\times x=138-72\)

\(2\times x=66\)

\(x=33\)

Answer 4

1 cái nữa thôi mà

Answer 5

(x+1)+(x+2)+(x+3)+...+(x+100)=7450

=> (x+x+x+...+x)+(1+2+3+...+100)=7450

100x + 5050 = 7450

100x = 7450 - 5050

100x = 2400

x = 2400 : 100

x = 24

2x-2³.3² = 138

2x-72 = 138

2x = 138-72

2x = 66

x = 66

x= 66:2

x = 33

(6x-3⁴).7³ = 3.74

=> (6x-81).343 = 222

6x-81 = 222:343

6x-81 = \(\frac{222}{343}\)

6x = \(\frac{222}{343}\) + 81

6x = \(\frac{28005}{343}\)

x = \(\frac{28005}{343}\) : 6

x = \(\frac{9335}{686}\)
