Step-by-step explanation:

$= ( {x}^{3} ) { ({x}^{7} )}^{2}$

$= {x}^{3} \times {x}^{7 \times 2}$

$= {x}^{3} \times {x}^{14}$

$= {x}^{3 + 14}$

$= {x}^{17}$

What is the solution to the equation?

AleksandrR [38]

Solution of the equation: $x=6\frac{1}{2}$

Step-by-step explanation:

The equation that we have to solve in this problem is:

$13\frac{3}{4}+x=7\frac{1}{4}$

The first step to do is to rewrite the mixed fractions as improper fractions. We have:

$13\frac{3}{4}=\frac{13\cdot 4+3}{4}=\frac{52+3}{4}=\frac{55}{4}$

And

$7\frac{1}{4}=\frac{7\cdot 4+1}{4}=\frac{29}{4}$

So the equation becomes

$\frac{29}{4}+x=\frac{55}{4}$

Now we multiply by 4 each term on both sides, and we get

$29+4x=55$

Now we subtract 29 from both sides,

$4x=55-29=26$

And finally, we divide both sides by 4:

$x=\frac{26}{4}=\frac{13}{2}=6\frac{1}{2}$

Misha Larkins [42]

Final Answer: $-12x + 1.5$

Steps/Reasons/Explanation:

Question: Which expression is equivalent to $-3(4x - 0.50)?$

<u>Step 1</u>: Expand by distributing terms.

$-3$ × $4x - 3$ × $-0.50$

<u>Step 2</u>: Simplify $-3$ × $4x$ to $-12x$ .

$-12x - 3$ × $-0.50$

<u>Step 3</u>: Simplify $3$ × $-0.50$ to $-1.5$ .

$-12x - (-1.5)$

<u>Step 4</u>: Remove parentheses and add.

$-12x + 1.5$
