Question

(x^-4y^0z^2)^-2
a) x^8/y^2z^4
b) 1/x^8z^4
c) x^8/z^4
d) x^6y/z^4

anonymous · Answer

I solved the equation to 
c) x^8/z^4
Is this correct?

anonymous · Answer

oh wait.....by using exponent rule for negative exponents...If "a" is a real number other than "0" and "n" is an integer, then, a^-n=1/a^n and 1/a^-n=a^n. I attempted the equation again and solved to
b) 1/x^8z^4

jhonyy9 · Answer

x^-4 = 1/x^4
y^0 =1
z^2 =z^2
so than your exercise will be ( (z^2)/(x^4) )^-2

so than  

           1                          1                x^8
--------------- =  ----------- = ------
 ((z^2)/(x^4))^2          (z^4)/(x^8)      z^4

hope so much that is understandably

good luck
