- Radicals: Simplify $\sqrt{16}$.
- Problem-Solving: If a rectangle has a length of 10 and a width of 4, what is the area?
-
Provide Solutions to Each Example
Show the solutions step-by-step:- For integers: $-5 + 7 = 2$.
- For fractions: $\frac{1}{2} + \frac{3}{4} = \frac{2}{4} + \frac{3}{4} = \frac{5}{4}$.
- For radicals: $\sqrt{16} = 4$.
- For problem-solving: Area $A = length \times width = 10 \times 4 = 40$.
The exercises related to the concepts are:
- Integer example: $-5 + 7 = 2$.
- Fraction example: $\frac{1}{2} + \frac{3}{4} = \frac{5}{4}$.
