square root 2 times square root 3 times square root 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 is the same as the square root of 4. Square root of 4 multiplied by square root of 2 is equal to the square root of 8.

8 to the saquare root of 2 is 64

8

The square root of 8 is 2 times the square root of 2 sqrt(8) = 2 x sqrt(2)

The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.

Sq root of 2 * sq root of 8 = 1.414 * 2.828 = 3.998792

To get the square root of 8, you have to multiply the root of 2 and the root of 4. The root of 4 then simplifies to 2, so the square root of 8 equals 2 times the square root of 2.

You have to find what times itself 3 times will equal 8. So 2x2x2 equals 8

It is: 2 times the square root of 2

It could be: 7/8 times 7/18 = 49/144 and its square root is 7/12

it would be Root 2 X Root 2 X Root 2 = equals Root 8. I believe that is what your asking....

How about 2 times 4 = 8 or 1 times 8 = 8

=SQRT(5)*SQRT(2)+SQRT(8) is 5.99070478491457

To cube a number, you would multiply the number three times. The cube root is the root of the number before it is multiplied. For example, 2 times 2 times 2 is 8, so the cube root is 2.

The numbers are: 8 times square root of 15 and 8 times the square of 15

The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8

the square root of 4 is 2 so you just multiply 4 times 2. the answer is 8

Square roots, simplifiedWhen you are asked for a simplified square root of some number, the answer is expected to be in radical form, not in decimal form. For example, 3 radical 2 (or three square roots of two) is the simplified square root of 18.So, let's look at this one: the square root of 8.The factors of 8 are 4 and 2. (8 and 1 are also factors, but those are not helpful.) So we can say that the square root of 8 is equal to the square root of (4 times 2):SQT(8) = SQT(4 * 2)This can be written another way:SQT(8) = SQT(4) * SQT(2)Since 4 is a perfect square whose square root is 2, we can write the equation above this way:SQT(8) = 2 * SQT(2)In English, that's "The square root of 8 is 2 square roots of 2" or "The square root of 8 is 2 times the square root of 2" or "The square root of 8 is 2 radical 2."What's this radical business? Well, I can't draw the radical sign here, so I've been using the SQT(x) convention. That is equal to an x under a radical sign.By the way, 2 times the square root of 2 is 2.828, if you are wondering.

2 times square root of 2 times i (where "i" is the imaginary unit).

it is the square root of 16 which equals 4.

2*2*2 = 8 8*3 = 24

8 times -1/8=-8/8, and -8/8 is -1, -1-1=2

-2 - 2i and -2 + 2i where i is the imaginary square root of -1.
