Select the equivalent expression for the following: 12^3 * 12^9 * 12^4 * 12^2 a:
12^18
b:
12^216
c:
20,736^18
d:
2.66 *10^19

9514 1404 393

  a:  12^18

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)(a^c) = a^(b+c)

__

All of the bases are the same in this expression, so the exponents add:

  12^3 * 12^9 * 12^4 * 12^2 = 12^(3+9+4+2) = 12^18 . . . . matches choice A

y > 1/3x

y < = -x + 4

hope this : )

this is answer of 144 cubic meters
