Answer 3

use the idea

Numbers, Letters, Powers Signs....

so its 3*5xyz

add the powers for each letter (the index law for multiplication)

\[x^a \times x^b = x^{a+b}\]

and since both terms are positve the answer is positive...

last thing to know about powers

a single letter is really

\[x = x^1\]
