Question

7x- 2x=6^17:6^15+44:11

Answer 1

7x - 2x = 6¹⁷ : 6¹⁵ + 44 : 11

7x - 2x = 6² + 4

7x - 2x = 40

5x = 40

x = 8

Answer 2

7x-2x=6^17:6^15+44:11

5x=6^17-15+4

5x=6^2+4

5x=36+4

5x=40

x=8

chúc bn hok tốt

Answer 3

\(7x-2x=6^{17}:6^{15}+44:11\)

\(5x=6^2+4\)

\(5x=36+4\)

\(5x=40\)

\(x=40:5\)

\(x=8\)

Vậy \(x=8\).

Answer 4

\(7x-2x=6^{17}:6^{15}+44:11\)

\(\Leftrightarrow5x=6^{17-15}+4\)

\(\Leftrightarrow5x=6^2+4\)

\(\Leftrightarrow5x=36+4\)

\(\Leftrightarrow5x=40\)

\(\Leftrightarrow x=40:5=8\)

Vậy \(x=8\)

Chúc bạn học tốt!!!
