Answer 1

Hey Buddy

Here's The Answer

------------------------------------------------

=> 3ˣ⁺³ = 9ˣ⁺¹

Firstly we'll try to equalize the base, 9 can be written as 3²

=> 3ˣ⁺³ = 3²⁽ˣ⁺¹⁾

Now the bases are same, and powers can be compared

=> x + 3 = 2( x + 1 )

=> x + 3 = 2x + 2

=> 2x - x = 3 - 2

=> x = 1 ✓

Hope It Helps.
