Question

Prove that 3 power p + 1 - 3 power P upon 2 multiply 3 power p is equal to 1 ​

Answer 1

see explanation

Explanation:

note that
`3^(p+1)` =
`3^(p)` × 3 ( when multiplying exponents are added )

Given

`(3^(p+1)-3^(p) )/(2.3^(p) )` ← factor out
`3^(p)` on numerator

=
`(3^(p)(3-1) )/(2.3^(p) )`

=
`(2.3^(p) )/(2.3^(p) )`

= 1
