Answer:
Step-by-step explanation:
= a^21b^24c^10
use the product rules for each set of () then multiply them together. when multiplying variables with exponents you just add them together like for a^3 * a^5 = a^8. (a^3 b^12 c^2)^2 = (a^6 b^24 c^4)
I believe it is ; for the number
1 mile = 1.6 km
x = 50 × 1.6
x = 80 miles
