Answer:
1) 504 miles 2) 4,200 miles
Step-by-step explanation:
X = - 4; y = 3; z = 2;
2 x² - 2 z^4 + y² - x² + z^4 =
= 2 * (-4)² - 2 * 2^4 + 3² - ( -4)² + 2^4 =
= 2 * 16 - 2 * 16 + 9 - 16 + 16 =
= 32 - 32 + 9 - 16 + 16 = 9
9: x^15-8
= x^7
10: n^22-13
= n^9
11: (x^3)^-9
= x^3*-9
=x^-18
=1/x^18
12: (ab)^4
=a^4*b^4
13: x^-5
=1/x^5
14: x^7\y^7
I hope this will help you
