Vocabulary Exponents: an exponent is a number that shows how many times a base is multiplied Scientific notation : It is a way of expressing a number, a number is expressed in scientific notation when it is written as the product of a number.
Vocabulary Cube: A cube is a rectangular prism with six congruent faces. Cube Root: the cube root of a given number is a number whose third power is the given number
Vocabulary Hypotenuse: in a right triangle the hypotenuse is the longest side which is opposite the right angle. The legs of a triangle: legs of a triangle are the two shorter sides of the triangle.
Vocabulary Right triangle: A right triangle is a triangle with one right angle Square: a square is a parallelogram with four right angles and four congruent sides
Vocabulary Square Root: the square root of a given number is a number that when multiplied by itself equals the given number Radical: The radical is the Square root symbol
Vocabulary Radicand: the radicand is the number inside Principal: a positive square or a potential root Base: a repeated factor of a number written in exponential factor
Vocabulary Power: a power is any expression in the form a power is also used to refer to the exponent perfect square: a perfect square is the square of an integer
Properties of Exponents Division: Steps: 1. Rewrite expression 2. Put the same exponent that is outside the parentheses in the numerator next denominator 3. Make the parentheses outside the original exponent of the base that is the numerator 4. multiply the base 3 times by itself that is the numerator 5. Multiply the exponent that was inside the parentheses by the original exponent 6. multiply the exponents in the denominator
7. write solution in the form of a fraction, leaving the same base and the product of the exponents as the denominator
Writing in Scientific Notation write 0. 000079 in scientific notation? steps: 1: move the decimal point to get a decimal greater than one but less than ten. 2: drop the zeros before the 7 3: you moved the decimal 5 places, the orignal number is less than 1.
Multiplication in Scientific Notation 1. Use the commutative property of multiplication 2. Multiply 3 & 9 3. Add the exponents 4. Write 27 as 2. 7 times 10 to the first power 5. Add the exponents
