The sum of 36 plus 63 can be expressed as a product by first calculating the sum, which is 99. This can be factored and expressed as a product of its prime factors: (99 = 9 \times 11), or as (3^2 \times 11). Thus, the expression for the sum of 36 and 63 as a product is (9 \times 11).
7(7 + 9)
They are: 78 and 63
"x" is the symbol for product or multiple: not sum. Consequently the question is unclear.
To find two numbers whose sum is 16 and product is 63, we can set up the equations ( x + y = 16 ) and ( xy = 63 ). By substituting ( y = 16 - x ) into the product equation, we get ( x(16 - x) = 63 ), which simplifies to ( x^2 - 16x + 63 = 0 ). Solving this quadratic equation, we find the numbers are 7 and 9, as ( 7 + 9 = 16 ) and ( 7 \times 9 = 63 ).
