What is radical 14 times radical 2?

radical(14)*radical(2) = 2*radical(7)

Without further information available we will consider only the square roots. The square roots of 14 are +3.741 and -3.741, similarly the square roots of 2 are+1.414 and -1.414 and so we can have four products

1) (+3.741) X (+1.414) = +5.155

2) (-3.741) x (+1.414) = -5.155

3) (+3.741) x (-1.414) = -5.155

4) (-3.741) x (-1.414) = +5.155

Expressions 1 and 4 are equal, expressions 2 and 3 are equal. Hence the product of radical 14 times radical 2 can be +5.155 or -5.155
