hi help i need your questions step by step answer ok

Answer:
Step-by-step explanation: Recall a^0 =1
1) 1-1-1=0
1b) (5^3)^2 x 5^-5
5^6 x 5^-5
5^6+(-5)
5^6-5 =5^1 =5
1c) 9^6 ÷ 3^12
(3^2)^6 ÷ 3^12
3^12 ÷ 3^12
3^12-12 =3^0 =1
2a) (-4x7)^-3
(-28)^-3
= (1/-28)^3
2b) 27^3 x 3^-6
27^3 x 1/3^6
(3^3)^3 x 1/3^6
3^9 x 1/3^6
3^9/3^6
3^9-6
3^3 = 27
2c)( x^4 y^3 Z^2)^-2
-------------------
( x y^2 Z^4) ^-2
= ( x^3 y / z^2 )^-2
(1/x^3 y/z^2)^2
(1 X Z^2/x^3 y) ^2
ans = (z^2/x^3 y)

Hope it works.................................™✌️✌️
