Answer:

OPTION - 3: -m²n³$ \sqrt{n} $

Step-by-step explanation:

We know that $ \sqrt{ab} = \sqrt{a}\sqrt{{b} $

Also, $ \sqrt{m^{2}} = m $

Now we are to simplify: $ - \sqrt{m^4n^7} $

$ \implies - \sqrt{m^4}\sqrt{n^7} $

$ \implies - \sqrt{(m^2)^2}\sqrt{n^6.n} $

$ \implies-  m^2 \sqrt{(n^3)^2.n} $

$ \implies - m^2 n^3\sqrt{n}

∴                       $ \sqrt{m^4n^7} =  -m^2n^3\sqrt{n} $

Jake needs to put gas in the delivery van regular gasoline is 3.20 per gallon he only had a $20 bill on him how many gallons can
Fed [463]
Your max amount for this is $20. Let's say x represents the number of gallons.

20 ≥ 3.2x
x = 6.25 gallons
If they're asking for integers or whole numbers, you'd round down to 6 because you only have enough money for 6 full gallons. If you rounded up to 7, you wouldn't be able to fill it up completely because then you'd be over your $20.00 budget for gas.
