Answer:
B a b^2 c^5/ d^4
Step-by-step explanation:
a^-3 b^2 c^3 d^-3 / (a^-4 b^-2c^-2d)
separate the terms
a^-3/a^-4 * b^2/b^-2 * c^3 /c^-2 d^-3 /d
when dividing, we subtract the exponents
a^ (-3--4) b^(2--2) c^(3--2) d^(-3-1)
a^ (-3+4) b^(2+2) c^(3+2) d^(-3-1)
a^1 b^2 c^5 d^-4
negative exponent go to the denominator if they are in the numerator
a b^2 c^5/ d^4

Answer: Definition: Ratio of the size of the map to its subject: Scale ... so scale = 1 cm / 100,000 cm = 1/100,000. - Scale ... STEP 1: - 2 cm represents 5 km
Step-by-step explanation:
STEP 1: - 2 cm represents 5 km - (write in full)
- STEP 2: - 1 cm represents 2.5 km - (divide so left side = 1)
- STEP 3: - 1 cm represents 250,000 cm - (convert to same units)
- STEP 4: - scale is 1 : 250,000 - (express as a representative fraction)
