18%=0.18
380×0.18=68.4 increase
380+68.4=448.4
the easier way is to think 1 times any number is the same number so 380(1+0.18)=448.4 (just like adding tax to the price of something to see how much you'll actually pay)
<span>x^2 • y^–3 • x^4
= x^6 / y^3</span>
0 + -4 = -4
the 0 has no value and cannot add anything on top of the -4
So -4 stays the same:)
Answer = -4
Good Luck! :)
