Question 1 (Multiple Choice Worth 2 points) (MC) Rewrite the radical as a rational exponent. the fourth root of 7 to the fifth power 7 to the 5 over 4 power 720 7 7 to the 4 over 5 power -------------------------------------------------------------------------------- Question 2 (Multiple Choice Worth 2 points) (MC) Rewrite the rational exponent as a radical by extending the properties of integer exponents. 2 to the 7 over 8 power, all over 2 to the 1 over 4 power the eighth root of 2 to the fifth power the fifth root of 2 to the eighth power the square root of 2 to the 5 over 8 power the fourth root of 2 to the sixth power -------------------------------------------------------------------------------- Question 3 (Multiple Choice Worth 2 points) (MC) A rectangle has a length of the cube root of 81 inches and a width of 3 to the 2 over 3 power inches. Find the area of the rectangle. 3 to the 2 over 3 power inches squared 3 to the 8 over 3 power inches squared 9 inches squared 9 to the 2 over 3 power inches squared -------------------------------------------------------------------------------- Question 4 (Multiple Choice Worth 2 points) (MC) Explain how the Quotient of Powers was used to simplify this expression. 5 to the fourth power, over 25 = 52 By simplifying 25 to 52 to make both powers base five and subtracting the exponents By simplifying 25 to 52 to make both powers base five and adding the exponents By finding the quotient of the bases to be one fifth and cancelling common factors By finding the quotient of the bases to be one fifth and simplifying the expression -------------------------------------------------------------------------------- Question 5 (Multiple Choice Worth 2 points) (MC) Rewrite the rational exponent as a radical expression. 3 to the 2 over 3 power, to the 1 over 6 power the sixth root of 3 the ninth root of 3 the eighteenth root of 3 the sixth root of 3 to the third power

@iambatman can you help with a few plzzz

OpenStudy (anonymous):

Sure, which problem exactly?

OpenStudy (anonymous):

as many as possible plz lol but can we start with the first one? And thank you

OpenStudy (anonymous):

I just started the lesson and I don't know how to do this lol

OpenStudy (anonymous):

Number 1 is just saying \[\sqrt[4]{7}^{5}\]

OpenStudy (anonymous):

\[\huge x ^{\frac{ m }{ n }} = \sqrt[n]{x ^{m}} = (\sqrt[n]{x})^{m}\]

OpenStudy (anonymous):

whoa lol

OpenStudy (anonymous):

^ that's what our exponent rules tell us :P, can you see deduce what the exponent will be?

OpenStudy (anonymous):

yes its 16807

OpenStudy (anonymous):

I mean using exponent rules what will we get? |dw:1399587723336:dw|
