The divergence of <em>F</em> is
div(<em>F</em> ) = ∂(<em>x</em> + <em>yz</em>)/∂<em>x</em> + ∂(<em>y</em> + <em>xz</em>)/∂<em>y</em> + ∂(<em>z</em> + <em>xy</em>)/∂<em>z</em>
div(<em>F</em> ) = 1 + 1 + 1
div(<em>F</em> ) = 3
there are 25 girls. you can figure this out by adding 5 and 8 to find that there are 5 girls for every 13 students. then you have to find how many times 13 fits into 65. in this case it is 5. knowing this you can multiply the 5 girls by 5 to find that there are 25 girls in a class of 65 students
Thirty billion six hundred fifty thousand and eight
Answer:
if you meant y^8*y^2 then y^10 if you meant 8y*2y then 16y^2
