The answer 5 and 3/7 because you know that 7 goes into 38 five times, and 7 times 5 is 35. So since 38 minus 35 is 3, you get 5 as your whole number, and 3/7 as the fraction on the side.
5^-2 = 1/25
4^3 = 64
7^-2 = 1/49
9^2 = 81
Answer:
(xx*2)+3
you have to find twice as many before adding three
( x^4 - 4 x³ + 2 x² - 4 x + 1 ) : ( x² + 1 ) = x² - 4 x + 1
- x^4 - x²
------------------------
- 4 x³ + x² - 4 x
4 x³ + 4 x
-----------------------
x² + 1
- x² - 1
----------------
R ( x ) = 0
( x^4 - 4 x³ + 2 x² - 4 x + 1) = ( x² + 1 ) ( x² - 4 x + 1 )
36/100 = 0.36
0.36 * 2400 = 864
