This is for students in High School/College learning algebra. If you are a beginner in algebra you might be thinking X+Y=XY, Is not it? But itâs not. The beauty of algebra is, it deals with variables, expressions & equations. You will come to know various formulas. For example if you know (a+b)^3= a^3+b^3+3a^2b+3ab^2. You can calculate any number to the powers 2,3,4â¦in a fraction of seconds. In the above equation a ,b are variables. So you can calculate (1.034)^3 also using that formula. Just feed a=1& b=.034 IMathPractice Algebra's 3 steps method of teaching has sections like T
Master Algebra Lite is a free educational mobile app By ongolearn.com.It helps students in grades HS practice the following standards HSN.RN.A.1,HSN.RN.A.2,HSN.RN.B.3.
1. HSN.RN.A.1 : Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 51/3 to be the cube root of 5 because we want (51/3)3 = 5(1/3)3 to hold, so (51/3)3 must equal 5.
2. HSN.RN.A.2 : Rewrite expressions involving radicals and rational exponents using the properties of exponents..
3. HSN.RN.B.3 : Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational.
