Question

using appropriate formula, find the value of each of the following 5.9²​

Answer 1

Answer:

37.21

Step-by-step explanation:

5.9² can be written as (6-0.1)²

(6-0.1)² is in the form of (a-b)²

we already know that (a-b)²=a²+2ab+b²

Hence 6²+2×6×0.1+0.1²

   =  36+1.2+0.01=37.21

Answer=37.21
