Answer:
<u><em>8,126,500</em></u>
Step-by-step explanation:
Use order of operations and deal with the multiplication first
(81265 * 169) - (81265 * 69)
13,733,785 - 5,607,285
<u><em>8,126,500</em></u>
Answer: the number of variations in sign = 3
Step-by-step explanation:
Let the finite sequence 1, –3, 2, 5, –4, –6 , the only pairs of consecutive terms for which the product of the two consecutive terms is negative are :
{1, –3} ; {–3, 2}; {5, –4} then
the number of variations in sign = 3
