7x - 2x = 6^17 : 6^15 + 44 : 11
tìm x
Tìm x:
7x-2x=6^17:6^15+44:11
\(7x-2x=6^{17}:6^{15}+\dfrac{44}{11}\)
= \(7x-2x=6^{17}:6^{15}+4\)
= \(7x-2x=6^{17}:6^{15}+4\)
=\(7x-2x=6^2+4\)
=\(7x-2x=36+4\)
= \(7x-2x=40\)
=> x.(7-2)= 40
=> x.5=40
=> x=8
\(7x-2x=6^{17}:6^{15}+44:11\)
tìm x
\(7x-2x=6^{17}:6^{15}+44:11\)
\(\Rightarrow5x=6^2+4\)
\(\Rightarrow5x=36+4=40\)

tick cho mk nha bạn thùy nguyễn
7x-2x=617/615+44/11
(7-2)x=617-15+4
5x=62+4=36+4
x=40/5
x=8
7x- 2x=6^17:6^15+44:11
7x - 2x = 617 : 615 + 44 : 11
7x - 2x = 62 + 4
7x - 2x = 40
5x = 40
x = 8
7x-2x=6^17:6^15+44:11
5x=6^17-15+4
5x=6^2+4
5x=36+4
5x=40
x=8

7x - 2x = 617 : 615 + 44 : 11
\(\Rightarrow\) 5x = 62 + 4
\(\Rightarrow\) 5x = 36 - 4
\(\Rightarrow\) 5x = 32
\(\Rightarrow\) x = 6,4
7x - 2x = 617 : 615 + 44 : 11
7x - 2x = 62 + 4
7x - 2x = 36 + 4
7x - 2x = 40
x(7 - 2) = 40
x5 = 40
x = 40 : 5
