Four students are asked to write an equivalent form for v 72. The response of each student is given. Kat's response: My calculator says the value of v 72 is 8.48528137424, so the exact value of V72 is 8.48528137424. Lee's response: V72 can only be represented by v72; there are no other forms that have the same exact value since 72 is not a perfect square. Sam's response: 6y2 is the only form that has the same exact value as v 72. Terry's response: 218,3/8, and 6y2 are some forms that have the same exact value as y72. Which of the following student's response is accurate and why? Kat is correct. The calculator provides an exact value for the square root of any number. B Lee is correct. There is no equivalent form of v72. Sam is correct. Only the simplest radical form can be an equivalent form of the square root of any number.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction
