Question

tìm x

( x-1) ^8 = x- 1 

5.25^x = 125^8

Answer 1

5.25^x=125^8

125^x=125^8

=>x=8

Answer 2

5.25^x = 125⁸ 

=> 125^x = 125⁸ 

=> x     = 8 

Answer 3

\(\left(x-1\right)^8=x-1\)

\(\Rightarrow x-1=1\)

x = 1 + 1

x = 2

\(5\cdot25^x=125^8\)

\(5\cdot5^{2x}=5^{3\cdot8}\)

\(5^{1+2x}=5^{24}\)

\(\Rightarrow1+2x=24\)

2x = 23

x = \(\frac{23}{2}\)

Answer 4

( x-1) ^8 = x − 1
⇒x − 1 = 1
x = 1 + 1
x = 2

Vậy x=2
5.25^x = 125^8 

5.5^(2x)=5^(3.8)
5^(1+2x)=5^24

=>1+2x=24

=>2x=23

=>x=23/2

Vậy x=23/2
