how do you solve an equation in absolute signs? (4x - 2) = 10
e.g. |4x - 2| = 10 AND
(4x - 2) = -10
how do you solve an inequality in absolute signs? e.g. |4x (4x - 2) < 10
- 2| < 10 AND
(4x - 2) > -10
divisibility test for 7 separate the units digits from the rest of the number, then multiply that unit digit
by 2. subtract from what's left of the original number. if the result is a multiple of 7
or 0, the original number is a multiple of 7.
a^b x a^c = a^(b+c)
a^b / a^c = a^(b-c)
a^(-b) = 1 / (a^b)

the result is...
when a negative number is raised to an odd exponent, negative
the result is
√ab = ? (√a) x (√b)
√(a/b) = (√a) / (√b)
√(a+b) ≠ (√a) + (√b)
