Understanding Square Roots and Exponents

In this episode, Mr. Baskin covers various math topics for grade eight students. The lesson begins with an introduction to square roots, explaining how to approximate them and plot them on a number line. The video then moves on to solving equations involving square roots and negative solutions. It also covers identifying irrational numbers and converting numbers into scientific notation. Finally, the lesson concludes with an analysis of scatter plots to identify outliers. Throughout the video, Mr. Baskin provides clear explanations and examples to help students understand these mathematical concepts.

How can you determine that the square root of 37 is slightly more than 6?

• Because 37 is less than 64, and the square root of 64 is 8.

• Because 37 is more than 25, and the square root of 25 is 5.

• Because 37 is less than 49, and the square root of 49 is 7.

• Because 37 is more than 36, and the square root of 36 is 6.
