Question

please answer Q6…………:)

Answer 1

Solution:-

given by:-

n is prime number

${a}^{2} being \: divisible \: by \: p \\ {a}^{2} = n \times k \\ a \times a = n \times k \\ \frac{a \times a}{n} = k$
by (euclid's lemma)

∵( p|ab=>p|a or p|b or both)

hence proved a is also divisible by n.

varification:-

n = 2 is prime number

a^2 = 16

a = 4

both are divisible by 2 .
