Question

How do you solve `\sqrt { 0.25} \times \sqrt { 2}`?

Answer 1

See a solution process below:

Explanation:

Use this rule for multiplying radicals:

`sqrt(color(red)(a)) * sqrt(color(blue)(b)) = sqrt(color(red)(a) * color(blue)(b))`

`sqrt(color(red)(0.25)) * sqrt(color(blue)(2)) => sqrt(color(red)(0.25) * color(blue)(2)) => sqrt(0.5)`

Or

`sqrt(0.25) xx sqrt(2) = 0.5sqrt(2)`
