Write the following ratio using two other notations. 7 to 6

For what value of (y) is 3^3/3^y =1/9

Evaluate the expression. (9 + 5)(3 + 2)0

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
