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
520 x 0.2 = 104
520 + 104 = 625
Curtley's annual heating cost before he got his loft insulated was $624.00
Its b, c, and e but I’m not sure about d
Answer:
1. a^mn= (a^m)^n
2. a^m+n= a^m • a^m
3. 1= a^0
4. a^m • b^m = ab^ m
5. 1/a^n = (a)^m
Step-by-step explanation:
^ means exponent
• means multiply
