It is: 2 times the square root of 21 and it's an irrational number
First note that 84=4x21 and 4 is a perfect square. So square root of (84)=square root (4x21)=Square root (4) Square root (21)= 2 multiplied by the square root of 21. You can also write this using rational exponents, but this is not in radical form. It is an equivalent expression, however. 2 x (21)1/2
1x21=21 2x21=42 3x21=63 4x21=84 5x21=105 6x21=126 7x21=147 8x21=168 9x21=189 10x21=210
