tim x biet 125.5^x+5^(x+1)=3250
tim x:
5^x+5^x-2=3250
5^x+5^x+2=3250 ?
tim x
5^2x-1 = 125.5^4
7^x-3.4=196
2^x.2^x+3=64^2:2^5
( 37 + 18 ) . { 3250 - 152 x [ ( 44 - 25 ) : 16 ]}
125.5x-3=57
Nếu 5x : 5y = 125.5 4 thì x - y
Nếu 5x : 5y = 125.5 4 thì x - y bằng bao nhiêu
tìm x thuộc n biết
(2 x-5)4=265
(x-13) =(x-3)8
5x +5x+2=3250
