IM 8.8.1 Practice: The Areas of Squares and Their Side Lengths

Find the area of each square. Each grid square represents 1 square unit.

Find the length of a side of a square if its area is:

81 square inches

[math]\frac{4}{25}cm^2[/math]

0.49 square units

[math]m^2[/math] square units

Find the area of a square if its side length is:

3 inches

7 units

100 cm

40 inches

[math]x[/math] units

Evaluate [math](3.1\times10^4)\cdot(2\times10^6)[/math]. Choose the correct answer:

[math]5.1\times10^{24}[/math] [math]6.2\times10^{10}[/math] [math]6.2\times10^{24}[/math] [math]5.1\times10^{10}[/math]

Noah reads the problem, “Evaluate each expression, giving the answer in scientific notation.” The first problem part is: [math]5.4\times10^5+2.3\times10^4[/math].[br][br]Noah says, “I can rewrite [math]5.4\times10^5[/math] as [math]54\times10^4[/math]. Now I can add the numbers: [math]54\times10^4+2.3\times10^4=57.3\times10^4[/math]."[br][br]Do you agree with Noah’s solution to the problem? Explain your reasoning.

Select [b]all[/b] the expressions that are [math]3^8[/math].

[math]3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3[/math] [math]\frac{3^6}{3^{-2}}[/math] [math](3^4)^2[/math] [math]3^6\cdot10^2[/math] [math]8^3[/math] [math](3^2)^4[/math]
