\(2x^5+2=4\\ 2x^5=4-2\\ 2x^5=2\\ x^5=2:2\\ x^5=1\\ x=1\)

k mk nha!

thanks!

nhanha!!!

\(\Leftrightarrow220+16+x-5=64.5=320\\ \Leftrightarrow231+x=320\\ \Leftrightarrow x=89\)

giúp em tui với

10

\(\dfrac{23}{6}\)

\(\dfrac{3}{4}\)

\(\dfrac{9}{70}\)

6 x5/3=10   7:8/4+1/3=23/6     2x5/8-1/2=3/4   3/7:5/6x1/4=9/70

\(3^2.5+2^3.10-3^4:3\)

\(=5\left(3^2+2^3.2\right)-3^{4-1}\)

\(=5\left(9+16\right)-3^3\)

\(=5.25-27\)

\(=125-27=98\)

\(3^2\times5+2^3\times10-3^4:3\\ =9\times5+8\times10-27\\ =45+80-27\\ =98.\)

                                     32.5+23.10−34:3

=5(32+23.2)−34−1                                      =5(32+23.2)−34−1

=5(9+16)−33                                      =5(9+16)−33

$=5.25-27$

$=125-27$

$=98$

x=0;1;2;3;4;5;6;7;8;9

y=0

\(\dfrac{51}{14}\)

=51/14

\(4-\dfrac{1}{2}\times\dfrac{5}{7}=4-\dfrac{5}{14}=\dfrac{51}{14}\)

=6x^7+8x^5

Lời giải:

$2x^5(3x^2+4)=2x^5.3x^2+2x^5.4=6x^7+8x^5$
