Answer:
a = -2 z^-3 c^6
Step-by-step explanation:
equations are given as
a = 2b^3 .....1 and
b = -1/ z c^-2 .....2
put the value of b in eq 1
a = 2(-1/z c^-2)^3
a = 2(-1/z^3 c^-6)
or a = -2 z^-3 c^6
Answer:
see explanation
Step-by-step explanation:
step 4 take the square root of both sides
= ± 
x + 4 = ± 
step 5 subtract 4 from both sides
x = - 4 ± 
step 6 solve for x
x = - 4 -
or x = - 4 +
