Question

1. What is the first step in estimating square roots?
2. What does LPS and HPS stands for?
3. What formula to be used in estimating square roots?

Answer 1

1)Key Strategy in Solving Quadratic Equations using the Square Root Method. The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side. After doing so, the next obvious step is to take the square roots of both sides to solve for the value of x.

2)High pressure sodium vapor (HPS) lights, similar to LPS lights, are a specific type of gas-discharge light (also known as a high intensity discharge, HID or arc light). The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp.

3)Estimate: Get as close as possible to the number you're trying to square root by finding two perfect square roots that gives a close number. Divide: Divide your number by one of the square roots you've chosen from the previous step. Average: Take the average of step 2 and the root.

Answer 2

Answer:

1. We will first put the number inside the square root sign in the middle of a number line, and then find the two closest perfect square numbers on its left and right hand side to make the best estimation.
2. High pressure sodium vapor (HPS) lights, similar to LPS lights, are a specific type of gas-discharge light (also known as a high intensity discharge, HID or arc light). The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp.
3. A square root is the inverse of squaring. What is an inverse? Inverses are opposites, so for example, the inverse of adding is subtracting. The inverse of multiplying is dividing. These are opposites of each other, and have an inverse relationship.
