Which number in the monomial 215x^18y^3z^21 needs to Be changed to make it a perfect cube ?

FinnZ [79.3K]

Hello from MrBillDoesMath!

Answer: 215

Discussion:

Let's start by rewriting the monomial as

215 x^18 y ^3 z^21

Now..

x^ 18 = (x^6)^3

y^3 = (y )^3

z^21 = (z^7)^3

So those terms are already cubes! The only remaining candidate is the number 215, which is not a cube.

Thank you,

MrB

3+1/2 (3 - x) <-7<br>solve inequality

astra-53 [7]

subtract 3 from both sides:

$\dfrac{1}{2}(3-x)$

Multiply both sides by 2:

$3-x$

Subtract 3 from both sides:

$-x$

Change sign to both sides (this implies that you should also change the inequality sign):

$x>23$
