Answer:
(a) 
(b) We use the property of exponent that when there is multiplication of two function then there exponent are added
Step-by-step explanation:
We have given expression

(a) We have to find the value of a
We know the property of exponent that when there is multiplication of two function then there is addition of exponent
So 


(b) We use the property of exponent that when there is multiplication of two function then there exponent are added
The answer to this is the 3rd option
Answer:
16 km is the answer
Step-by-step explanation:
a (Colton to parents' house) = 12 km
b = ?
c (parents' house to grandparents' house) = 20 km
According to the Pythagoras theorem,
a² + b² = c²
12² + b² = 20²
144 + b² = 400
b² = 400 - 144
b² = 256
b = 16
∴ Colton is 16 km away from his grandparents' house.
