Answer:  A. commutative property

Step-by-step explanation:

Given: If x = 3 + 4i and y = 5 + 6i,

Then x × y = y × x

  • The commutative property of multiplication says that two expressions can be multiplied in either order. The answer remains unchanged with by changing the order i.e. ab=ba, where a and b be any two real numbers  expressions .

Therefore the property of multiplication shown above is commutative property of multiplication.

Answer:

A=8.4063u^{2}

Step-by-step explanation:

Be the functions:

y=\frac{3}{x};y=\frac{3}{x^{2}}:x=7

according the graph:

\int\limits^1_7 {\frac{3}{x} } \, dx -\int\limits^1_7 {\frac{3}{x^{2} } } \, dx =3\int\limits^1_7 {\frac{1}{x} } \, dx -3\int\limits^1_7 {\frac{1}{x^{2} } } \, dx=3(\int\limits^1_7 {\frac{1}{x} } \, dx -\int\limits^1_7 {\frac{1}{x^{2} } } \, dx)=3[lnx-\frac{1}{x}](1-7)=3[(ln7-ln1)-(\frac{1}{7}-1)]=3[(1.945-0)-(0.1428-1)]=3*(1.945+0.8571)=3*2.8021=8.4063u^{2}
