Question

Find the smallest number which when added to 4050,the sum would be perfect square.
Please write step by step.​

Answer 1

Answer:

850

Step-by-step explanation:

The method used is trial and error method:

First (20)^2=400

(40)^2=1600 etc

But we need a number close to 4050 therefore go on doing;

(50)^2=2500; (60)^2=3600; (70)^2=4900

Therefore; 4900 is closest and a perfect square of 70

Therefore; 4050 + X=4900

Therefore; X=850.
