Question

(a+b)2 ;a=1/2 and b=2

Answer 1

Answer:

$\frac{25}{4}$

Step-by-step explanation:

a + b = $\frac{1}{2}$ + 2 = 2 $\frac{1}{2}$ = $\frac{5}{2}$, thus

(a + b)² = ($\frac{5}{2}$ )² = $\frac{5}{2}$ × $\frac{5}{2}$ = $\frac{5(5)}{2(2)}$ = $\frac{25}{4}$

Answer 2

Answer:

5

Step-by-step explanation:

(a + b)2. when a = 1/2 and b = 2

Substitute the values of a and b into the equation

= (1/2 + 2)2

= (2.5)2

= 5
