Math Exponents question, please help! Grade 9 math

So the question is (2b/5c)3 the 3 is little btw. Please help!

(2b/5c)³ =

(2b)³ / (5c)³ =

8b³ / 125c³

the 8 is just 2X2X2, three times because of the small 3, and so is the 125 (5X5X5).

(2b/5c)^3 can be written out as (2b)^3 / (5c)^3

So if we do this separately: 2b x 2b x 2b = 8b^3.

And now for (5c)^3: 5c x 5c x 5c = 125c^3.

So the final answer will be (8b^3) / (125c^3)

Btw the "^" means to the power of so the number following will be "little", hope this helps.

You have to take the cube of both the numerator and the denominator.
So it would be rewritten as
(2b)^3
----------
(5c)^3

Then you cube both the number and the variable and the final answer is

8b^3
--------
125c^3

and the ^3 just means a little 3

(2b/5c)^3 (raised to the exponent 3)
so you can raise the numerator to 3 and the denominator to 3
so that's (2 cubed times b cubed) divided by (5 cubed times c cubed)
(8b^3)/(125c^3)
