Simplify the expression (8+i)(2+7i)

Given : (8 + i)(2 + 7i)

⇒ (8 × 2) + (8 × 7i) + (i × 2) + (i × 7i)

⇒ 16 + 56i + 2i + 7i²

We know that i² = -1

⇒ 16 + 58i + 7(-1)

⇒ 16 + 58i - 7

⇒ 9 + 58i

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
