Question

For numbers 4-8, estimate the square root of the number indicated to the nearest whole number. Do not use a calculator. Write in simplest radical form.

\sqrt(50)
\sqrt(99)
\sqrt(32)
\sqrt(146)
\sqrt(40)

Answer 1

√50 is between √49 and √64. Since 50 is closer to 49, we estimate that √50 ≈ √49 = 7.

√99 is between √81 and √121. Since 99 is closer to 121, we estimate that √99 ≈ √121 = 11.

√32 is between √25 and √36. Since 32 is closer to 36, we estimate that √32 ≈ √36 = 6.

√146 is between √121 and √169. Since 146 is closer to 169, we estimate that √146 ≈ √169 = 13.

√40 is between √36 and √49. Since 40 is closer to 36, we estimate that √40 ≈ √36 = 6.
