How do you solve the following problem 1.4142 x 1.4142

Question

Multiplying decimals

Answer 1

I recognize that this is, APPROXIMATELY, √2•√2 so it's about 2.

 

otherwise, just do long multiplication, or use a calculator, to get something near 2 to 4 decimal places of accuracy.

Answer 2

1.4142 = √2

So √2 x √2 = 2
