What is the cube root of 512 m^2n^15

8

Step-by-step explanation:

It depends what mathematics you know

Perhaps the most basic way would be by approximation. You  could start with, say, 5. 5*5*5= 125. Then 5 is to small to be the cube root of 512.

Try 10: 10*10*10=1000: Too bi. But now we know that the number we want is between 5 and 10.

Try 8: 8*8*8=512.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
