Answer:
4^4·6^5·7^7 = 1,639,390,814,208
Step-by-step explanation:
Taking the cube root multiplies each exponent by 1/3.
((4^12)(6^15)(7^21))^(1/3) = (4^(12/3))·(6^(15/3))·(7^(21/3)) = (4^4)(6^5)(7^7)
3) Definition of a parallelogram
4) Alternate interior angles
5) Reflexive property
6) ASA property
Please say if I got anything wrong!

=

Multiply both sides by 15
6 =

Multiply both sides by c
6c = 30 Divide both sides by 6
c = 5
