5^102=25^?????????????????????
14^26 . 5^24 / 2^25 . 35^24
( 3 / 5 )^2018 . x = (3/5)^2016
giúp mình với
25^50=5^???????????????
☹
(9 mũ 2 nhân 3 mũ 3 phần 3 mũ 7 ) nhân 2018
1. Tìm x :
x^3 - 1/2 = (-3)/8
(2x - 1)^3 = -8
17 + "3^x" = 98 (3 mũ x nha)
(2x +3)^2 = 9/121
2. Tính
2.1/9 : (1/3)^2 + (201/202)^2018 .(202/201)^2018
giúp mình với ^^
\(\left(\frac{3}{5^{ }}\right)^{2x^{ }}=\frac{9}{25}\)
Tính m, n, p biết :
a, 1/3 m =1/81
b, (3/5)n=(9/25)5
c, (-0,25)p=1/256
1,Tính giá trị biểu thức :
A= 212 . 35 - 46 . 92 / (22 . 36 + 84 . 55) - 510 . 73 - 255 . 492 / (125.7)3 + 59 .143
a. (4x +7)2= 25 phần 36
b. ( 5+2x)3= -- 8
c. 3x ×9=243
d. 42x= ( -- 64 ) . ( -- 4 )\(\)
