Nhân đa thức đối xứng

(2\sqrt{3} -4)/(\sqrt{3} -1) + (2\sqrt{2} -1)/(\sqrt{2} -1) - (1+\sqrt{6} )/(\sqrt{2} +3)

=(2\sqrt{3} -4)(\sqrt{3} +1)/(\sqrt{3} -1)(\sqrt{3} +1) + (2\sqrt{2} -1)(\sqrt{2} +1)/(\sqrt{2} -1)(\sqrt{2} +1) - (1+\sqrt{6} )(\sqrt{2} -3)/(\sqrt{2} +3)(\sqrt{2} -3)

=3-\sqrt{3} -2+4+\sqrt{2} -1 +(\sqrt{2} -3+2\sqrt{3} -3\sqrt{6} )/7

= 2.900712176

Chris took a vacation trip to maine, where sales tax on taxable items is 5%. in maine, prepared food and lodging are taxed an ad
12345 [234]
So, it's just an annoying problem. Keep the tax rates in mind for each thing.
$70 of souvenirs mean the tax is 5% since it is not prepared food, lodging, or auto rentals.
$580 on prepared food means that has 7% tax because it is special.
$620 on the car has a 10% tax, as stated in the problem.
So do 70(1.05)+580(1.07)+620(1.1) to get $1376.1.0
