Simplify 3^3
= (9-27) + (27-3)
= (-18) + (24)
= 6
I just took the test. The correct answer is:
The nearest integer is 7 because the nearest perfect square root is 49. Answer is 7-8
There are fours ways to solve polynomial equations..........
Polynomial Equation Degree Example
Linear Equations 1 -3x + 1 = 4x + 5
Quadratic Equations 2 x2 – 6x + 9 = 0
Cubic Equations 3 x3 – 2x2 + 3x = -5
Quartic Equations 4 x4 – 2x2 = -4
It's really not that hard.....
100 - 45 - 20 (0.2 = 20%) - 12.5 (1/8 = 12.5%) = 22.5%
