Chapter 8: Q. 8.2TI (page 745)

Simplify: $(a) \sqrt{100}$
$(b) - \sqrt{121}$

Short Answer

Expert verified

The solutions for (a) and (b) are $10 a n d - 11$ respectively.

Step by step solution

01

Part (a). Step 1. Given information

The root: $\sqrt{100}$

02

Part (a). Step 2. Calculation

We have,

$\sqrt{100} = 10$

Since, $10^{2} = 100$

Therefore, the solution is $10$

03

Part (b) Step 1. Given information

The root: $- \sqrt{121}$

04

Part (b). Step 2. Calculation

We have,

$- \sqrt{121} = - 11$

Since, $11^{2} = 121$ and the negative is in front of the radical sign.

Therefore, the solution is $- 11$
