Chapter 8: Q. 8.9TI (page 748)

Estimate each root between two consecutive whole numbers: $(a) \sqrt{38} (b) \sqrt[3]{93}$

Short Answer

Expert verified

The solution of (a) is $6 < \sqrt{38} < 7$ and (b) is $4 < \sqrt[3]{93} < 5$

Step by step solution

Part (a). Step 1. Given information

The root: $\sqrt{38}$

Part (a) Step 2. Calculation

We have,

$\sqrt{38}$

Number	Square Root
5	25
6	36
7	49
8	64

$36 < 38 < 49$

$\sqrt{38}$ is between their square rootsrole="math" localid="1645458941171" $6 < \sqrt{38} < 7$

Part (b) Step 1. Given information

The root: $\sqrt[3]{93}$

Part (b). Step 2. Calculation

We have,

$\sqrt[3]{93}$

Number	Cube Root
3	27
4	64
5	125
6	216

$64 < 93 < 125$

$\sqrt[3]{93}$ is between their cube rootsrole="math" localid="1645458911884" $4 < \sqrt[3]{93} < 5$
