Expressions & Equations Part 1 8.EE.1 Expressions & Equations Part 1

8.EE.1 Defined Know and apply the properties of integer exponents to generate equivalent numerical expressions.

8.EE.1 In 6th Grade students wrote and evaluated simple numerical expressions with whole number exponents (ie. 53 = 5 • 5 • 5 = 125). Integer (positive and negative) exponents are further developed to generate equivalent numerical expressions when multiplying, dividing or raising a power to a power. Using numerical bases and the laws of exponents, students generate equivalent expressions.

8.EE.1 Students Understand Bases must be the same to use the law of exponents Exponents are subtracted when Bases are being divided (1) Exponents are added when Bases are being multiplied (2) A number raised to zero will always equal 1 (3) Exponents are multiplied when an exponent is raised to an exponent (4)

8.EE.1 Exponents are subtracted when bases are being divided Example: (2^2/2^6)=2^-4=1/16 Work Out Below:

8.EE.1 Exponents are added when Bases are being multiplied Example: (2^2 x 2^2)=2^4=16 Work Out Below:

8.EE.1 A number raised to zero will always equal 1 Example: (6^2/6^2)=6^0=(6/6)=1 Work Out Below:

8.EE.1 Exponents are multiplied when an exponent is raised to an exponent Example: (4^2)^2=(4^4)=256 Work Out Below:
