Question

5 mũ x + 2 - 5 mũ x + 5 mũ x+1

Answer 1

5^x + 2 - 5^x + 5^{x + 1} 

\(\Rightarrow\) 2 + 5^x+1 

Answer 2

   5\(^{x+2}\)  - 5^\(x\) + 5^\(x+1\)

= 5^\(x\).(5² - 1 + 5)

= 5^\(x\)(25 - 1 + 5)

= 5\(^x\).(24 + 5)

= 5^\(x\),29

= 29.5\(^x\)

Answer 3

   5\(^{x+2}\)  - 5^\(x\) + 5^\(x+1\)

= 5^\(x\).(5² - 1 + 5)

= 5^\(x\)(25 - 1 + 5)

= 5\(^x\).(24 + 5)

= 5^\(x\),29

= 29.5\(^x\)
