Multiply and simplify.

ANSWER

$8 {x}^{5} {y}^{7} {z}^{2}$

EXPLANATION

The given expression is

$2 {x}^{2} {y}^{3} {z}^{2} \times 4x {y}^{4} {x}^{2}$

We multiply out to obtain,

$= 2 \times 4 \times {x}^{2} \times x \times {x}^{2} \times {y}^{3} \times {y}^{4} \times {z}^{2}$

Recall that,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this rule to obtain,

$= 8 {x}^{2 + 1 + 2} {y}^{3 + 4} {z}^{2}$

This simplifies to
$= 8 {x}^{5} {y}^{7} {z}^{2}$

Write the series 2+4+6+8+...+100 in sigma notation

Ugo [173]

We need to write the sum in this form:

$\displaystyle \sum_{i=1}^N a_i$

So, we need to find an appropriate sequence, such that $a_i$ is the i-th even number.

You can easily check that this series is $a_i=2i$ . In fact, you have

$\begin{array}{c|c|c}a_1&2\cdot 1&2\\a_2&2\cdot 2&4\\a_3&2\cdot 3&6\\a_4&2\cdot4&8\end{array}$

and so on. Finally, we have to observe that we want the first 50 elements of this sequence, since $a_{50} = 2\cdot 50 = 100$ .

So, the sum can be written as

$\displaystyle \sum_{i=1}^{50} 2i$

length is 2x centimeters. Write a simplified equation to solve for x in terms of AT, the area of the tile. If necessary, use rat

Lelu [443]

i dont know if this is correct

AT (X)= 6X^2 another part to this equation is: AT/6= X^2 and the answer is X= AT/6^1/2b.
