Question

find x so that (5/4 ^-3 ) (5/4^11) =(5/4)^8x​

Answer 1

Answer:

= $x=1$

Step-by-step explanation:

here, $(\frac{5}{4}^{-3})(\frac{5}{4}^{11})=\frac{5}{4}^{8x}$

⇒ $\frac{5}{4}^{-3+11} = \frac{5}{4}^{8x}$

⇒ $\frac{5}{4}^{8}=\frac{5}{4}^{8x}$

⇒ $8x=8$

⇒ $x=\frac{8}{8}$

⇒ $x=1$

so, $x=1$
