When you multiply 2 by √2, you are essentially multiplying 2 by 2^(1/2). Using the properties of exponents, when you multiply two numbers with the same base, you add the exponents. Therefore, 2 * 2^(1/2) = 2^(1) * 2^(1/2) = 2^(1 + 1/2) = 2^(3/2). Simplifying this further, 2^(3/2) is equivalent to √(2^3) = √8.
A square root of a number is a number that, multiplied by itself once, will equal the first number. Meanwhile a cube root of a number is a number that, multiplied by itself twice, will equal the first number. For example: the square root of 4 is 2. [ 2 X 2 = 4 ] [ 2 times itself equals 4 ] : the cube root of 8 is 2. [ 2 X 2 X 2 = 8 ] [ 2 times itself, and then times itself again, equals 4 ]
2 times root 2= 2x2x2 = 8
root 8 = root 4 x root 2 = 2 root 2, root 18 = root 9 x root 2 = 3 root 2; 2 root 2 x 3 root 2 = 6 x 2 = 12
They are -3 and -5

-2 - 2i and -2 + 2i where i is the imaginary square root of -1.
√8 multiplied by 3√2 = 3.563594873 (when rounded)
The square root of 8 is 2 multiplied by the square root of 2

2 times root 2= 2x2x2 = 8
4*2=8
If the square root of 2 is multiplied together twice we get 2. Thus if it's multiplied 4 times we get 4. Thus if it's multiplied together 6 times we get 8. Thus if it's multiplied together 8 times we get 16. Thus if it's multiplied together 10 times we get 32. So 10 lots of root 2, all multiplied together, gives 32.
root 8 = root 4 x root 2 = 2 root 2, root 18 = root 9 x root 2 = 3 root 2; 2 root 2 x 3 root 2 = 6 x 2 = 12
They are -3 and -5
These are the pairs of numbers that when multiplied are equal to 64: (1, 64) (2, 32) (4, 16) (8, 8)
