To answer this question you need to know how to count formula of a rectangle. Area of a rectangle is count by length x width formula. Then if you put the number into the formula it would be:
area = length x width 0.8 square unit= 3.2 unit * x 3.2 x unit = 0.8 square unit x= 0.8 square unit / 3.2 unit= 0.25 unit
Answer 1) c. 9 inches squared 2) c. By simplifying 8 to 23 to make both powers base two and subtracting the exponents 3) b. 2 to the 7 over 3 power
Explanation. Question 1 The area of a rectangle is given by area=l×w =〖81〗^(1/3)×3^(2/3) 3^(4/3)×3^(2/3)=3^(4/3+2/3) =3^(6/3)=3^2=9 inches squared
Question 2 Finding the 2^5/8=2^2 The steps for finding this is first to write 8 as 23. Then divide. 2^5/8=2^5/2^3 When dividing exponents with the same base you subtract the powers. =2^(5-3)=2^2
Question 3 The question wants us to solve, ∛(3^7 ).the cube root of a number can be written as a power of a third. So, ∛(3^7 )=3^(7×1/3 ) =3^(7/3)
