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.

What is cube root and square root?
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 ]
Why does 2 times root 2 equal to 8?
2 times root 2= 2x2x2 = 8
Simplify the square root of 8 multiplied by the square root of 18?
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
What 2 numbers when multiplied equal 15 but when added equal -8?
They are -3 and -5
What is the square root of 64 divided by 8?
8
