5^2x-3-2.5^2=5^2x3
Tìm x, biết:
a)2.52.32+{[2.53-(5.x+4).5}}:(22.3.5)}=453
b)\(|x-\frac{1}{3}|=2\)
a) 5. ( 7 + 48 : x ) = 45
b) 5²x-³ - 2.5² = 5² . 3
5.3^x+6=2.5^5+3
a)5^x+1=125
b)5^2x-3-2.5^2=5^2.3
c)4^x.3=16
tim x biet 5^(2x-3)-2.5^2=5^2.3
5(x+3^2.5)=300
Tìm x, biết:
\(5^{x-11}-2.5^2=3.5^3\)
5^x+4-3.5^x-3=2.5^11
