Is the square root of eight a rational or irrational number
shutvik [7]
\bf \sqrt{8}\implies \sqrt{2\cdot 2\cdot 2}\implies \sqrt{2^2\cdot 2}\implies 2\sqrt{2}

it just so happen that √2 is an irrational number, so any product with it as a factor, will yield an irrational number as well.



factoid:   Ancient Greeks were scared of irrational numbers, and they steered clear from √2.

Answer:

A. x=0

Step-by-step explanation:

x+10x+9x

add x to 10x

move variable to left

11x-9x=0

subtract 11x to 9x

2x=0

divide Both sides by 2

x=0
