15. Since p=215. 851-p would be 851-215 which equals 636

18. Since a=6 and b=5 and c=3, ab/2 would be 6x5/2 which equals to 30/2. Now, you must add 30/2 to 4c. And again since c=3, it would be 4x3 which equals to 12. So now the equation would be 30/2+12. You must now turn the fraction into a whole number by 30÷2 which is 15. The question would now ask 15+12 so the answer would be 27

What is the following product? Sqr5x^8y^2 sqr10x^3 sqr12y

PSYCHO15rus [73]

Step-by-step explanation:

$\sqrt{5 {x}^{8} {y}^{2} } \times \sqrt{10 {x}^{3} } \times \sqrt{12y} \\ \\ = {x}^{4} y \sqrt{5} \times x \sqrt{10x} \times 2 \sqrt{3y} \\ \\ = 2 {x}^{5} y \sqrt{5 \times 10x \times 3y} \\ \\ = 2 {x}^{5} y \sqrt{5 \times 5 \times 2x \times 3y} \\ \\ = 2 {x}^{5} y \times 5\sqrt{ 2x \times 3y} \\ \\ = 10 {x}^{5} y \sqrt{6xy} \\$
