## Standards with the same topic and subject but for other grades

The power of a number represents repeated multiplication of the number (e.g., 8³ = 8 · 8 · 8). The base is the number that is multiplied, and the exponent represents the number of times the base is used as a factor. In the example, 8 is the base, and 3 is the exponent.

A number written in scientific notation is the product of two factors — a decimal greater than or equal to 1 but less than 10, and a power of 10 (e.g., 3.1 x 10⁵= 310,000 and 2.85 x 10-⁴ = 0.000285).

The symbol ∙ can be used in grade six in place of “x” to indicate multiplication.

Identify the perfect squares from 0 to 400. (d)

The examination of patterns in place value of the powers of 10 in grade six leads to the development of scientific notation in grade seven.

Any number, except zero, raised to the zero power is 1. Zero to the zero power (0⁰) is undefined.

The student will investigate and describe concepts of positive exponents and perfect squares.

The student will recognize and represent patterns with whole number exponents and perfect squares.

In exponential notation, the base is the number that is multiplied, and the exponent represents the number of times the base is used as a factor. In 8³, 8 is the base and 3 is the exponent (e.g., 8³ = 8 ∙ 8 ∙ 8).

Any real number other than zero raised to the zero power is 1. Zero to the zero power (0⁰) is undefined.
