Lizbeth says that (-12)^-3 equals a positive number because the product of two negative numbers equals a positive. is this true. explain

(-12)^-3

convert negative exponent into positive using formula x^(-m)=1/x^m

(because the product of two negative numbers equals a positive)

(because the product of negative and positive numbers equals a negative)

We see that final answer is negative while Lizbeth says it should be positive.

Hence given explanation is FALSE.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
