Question

please give the ans

Answer 1

Given: p = (-1)^205 and q = (-1)^202

To find: p + q

Answer:

Since we know the values of p and q (given) p + q = (-1)^205 + (-1)^202

The exponent on p is an odd number, hence p = -1.

The exponent on q is an even number, hence q = 1.

Therefore, p + q = 0.

Hope it helps :)

Answer 2

$\red{hey\:mate\:here's\:ur\:answer}$

as we know
${ - 1}^{odd } = - 1$
${ - 1}^{even} = 1$
therefore
${ - 1}^{205} = 1$
and
${ - 1}^{202} = 1$
therefore p= -1. and q= 1
so, p+q= (-1)+1=0
