Example of an exponent | 4x^2 |
Example of Powers of Binomials | 2(x-3)^2+10 |
Quadratic Formula | x equals fraction numerator minus b plus-or-minus square root of b squared minus 4 a c end root over denominator 2 a end fraction |
How do you solve square root of x=10 | You would take the problem to the second power to eliminate the square root. You would then do that to the other side as well. When you get 10^2 your answer will be 100. You then double check your work to see if the square root of 100 is 10. |
what is the square root of 18 | You would just solve this and you would ed up with 3 square roots of 2 |
Can there be unreal numbers? | Yes. That is when there is a negative. |
What does it mean to evaluate? | When we evaluate an expression, we are investigating its value when x , or the variable, is a certain value. |
What is 9^0 power? | 1 |
What is 3^-1 power? | 1/3 |
What is 3^-2 | 2/3 |
