GIÚP MK NHÉ, MK CẢM ƠN NHIỀU !!!
bài 1:Tìm x
9^x:3^x=22
3^-1.3^x+9.3^x=28
bài 2:Tính
(1000-1^3).(1000-2^3)..........(1000-2018^3)
------------------------------------Các bạn giúp mình với mik đang cần gấp------------------------
tìm soos nguyên x nếu biết
1/ 5.3\(^x\)= 5.3\(^4\)
2/ 9.5\(^x\)= 6.5\(^6\)+3.5\(^6\)
3 /2.3\(^{x+2}\)+ 4.3\(^{x+1}\)=10.3\(^6\)
Bài 1 Tính
a, 12/21-3/7+-2/3
b,(-25/13)+(-9/17)+12/13+(-25/17)
c,5/9.7/13+5/9.9/13-5/9.3/13
Bài 2 tìm x
a,2/3x+5/7=3/10
b,x:5/2-1/2=-2/3
c,|x-3/4|-1/2=0
Tìm x
a)\(5^{\left(x-2\right).\left(x+3\right)}=1\)
b)\(\left(7-x\right)^{x+1}-\left(x-7\right)^{x+11}\ne0\)
c)\(x.\left(6-x\right)^{2003}=\left(6-x\right)^{2003}\)
d)\(2.3^x=10.3^{12}+8.3^{12}\)
e)\(5^x+5^{x+2}=650\)
2.3x+24.3x+1=10.36
2Tìm X:
a.(19x+2.5^2):14=(13-8)^2-4^2
b.2.3^x=10.3^12+8.27^4
c.{x^2-[6^2-(8^2-9.7)^3-7.5]^3-5.3}^3=1
d.60-3(x-2)=51
e.4x-20=2^5:2^2
