9-1 Multiplying Monomials Objective: To find the area or volume of a shape. Standard 10.0
Negative numbers and Powers (-5)2 = (-5)(-5) = 25 (-5)3 = (-5)(-5)(-5) = -125 -52 = -(5)2 = -25 Even exponent = positive #, Odd exponent = negative #
TOO • (-3x)3 • -(4x5y)3 • (6xy5)(-3xy2)
Zero Power • Anything to the zero power is….. ? • 1
Find the area of the shape. Area = (length)(width) Example 1
Find the volume of the shape. Volume = (length)(width)(height) Example 2
Your turn! • Pick a shape: or • Label the sides with monomials • Don’t be afraid to use negative coefficients and fractions • Switch with a partner (across the aisle) • Partner will find area or volume • Switch back and check answer
Homework If your homework doesn’t make you smile, I hope this little guy does!! • 9-1 Practice (worksheet)
Whiteboards • Whiteboard • Sock • marker
