Answer:
0.37690
Step-by-step explanation:
(4a² -4a + 1 )+ 3a
=> ((2a)² - 2*2a + 1²) + 3a
using formula (a² -2ab + 1²) = (a-b)²
=> (2a-1)² + 3a
putting value of a = 0.1039
(2*0.1039 -1)² + 3 * 0.1039
= 0.37690

Given: √4a^2 - 4a + 1 + 3a
= √(2a)^2 - 2(2a)(1) + 1 + 3a
= √(1 - 2a)^2 + 3a
= (1 - 2a) + 3a
= 1 - 2a + 3a
= 1 + a
= 1 + 0.1039
= 1.1039
Hope this helps!
