Answer:
250
Step-by-step explanation:
You multiply 1 by 5 to get the 5".
Multiply 50 by 5 (the same number you multiplied the 1 by to get the 5)
50×5=250
Answer: D/3f^2 = e
Step-by-step explanation:
D = 3ef^2
Divide by 3f^2 on both sides.
D/3f^2=e, the first option.
The answer is x^2/3y^3 hopefully this is correct
4.5*10^3/9*10^7=4.5/9*10^3*10^7=0.5*10^3*10^7. a^b*a^c=a^(b+c), so 10^3*10^7=10^(3+7)=10^10. 0.5*10^10=5*10^9, since we want to write in scientific notation where the leading number is bigger than one and smaller than 10.
79 is a prime, so we cannot reduce it.
