How to find out the value of cube root of 512
We will find factors of the number 512 then we will take cube root of the number, it is a value which when multiplied by itself three times gives the original value, 512 So let’s start
Step 1: Now we will find the factors of 512.
512 is divisible completely by 1, 2, 4 ,8,16, 32, 64, 128, 256 and 512. So the Factors of1, 2, 4 ,8,16, 32, 64, 128, 256 and 512.The factors of 512 greater than 1 are, 2, 4 ,8,16, 32, 64, 128, 256 and 512
Step 2: If 8 is multiplied three times,
8*8*8 =512 the value is 512
Step 3: Hence 8 is considered to be the cube root of 512
Step 4: Therefore, we can say that the value of cube root of 512 is 8
Step 5: We express the value of cube root of 512 as ∛512 = 8
Since the cube root symbol is denoted by ∛
