<h3>Simplifying an expression</h3>

From the question, we are to simplify the given expression

The given expression is

$\frac{x^{8}y^{-26} }{x^{14}y^{-5} } \times x^{-39} y^{-21}$

The expression can be simplified as shown below

$\frac{x^{8}y^{-26} }{x^{14}y^{-5} } \times x^{-39} y^{-21}$

$\frac{x^{8} \times x^{-39} \times y^{-26} \times y^{-21} }{x^{14} \times y^{-5} }$

$\frac{x^{8+-39} \times y^{-26+-21} }{x^{14} \times y^{-5} }$

$\frac{x^{8-39} \times y^{-26-21} }{x^{14} \times y^{-5} }$

$\frac{x^{-31} \times y^{-47} }{x^{14} \times y^{-5} }$

Then,

$\frac{x^{-31} }{x^{14} } \times \frac{ y^{-47} }{ y^{-5} }$

$x^{-31-14} \times y^{-47--5}$

$x^{-31-14} \times y^{-47+5}$

$x^{-45} \times y^{-42}$

$x^{-45} y^{-42}$

Hence, the simplified form of the expression is $x^{-45} y^{-42}$

I HAVE LIKE 2 MORE QUESTIONS, HELP ME PLZ!

Ne4ueva [31]

Given:

Base length of triangle = 10 units

Height of triangle = $\sqrt{44}$ units

Length of hypotenuse of triangle = 12 units

To find:

Exact value of Cos A

Steps:

The cosine of any angle is equal to the length of the adjacent side by the length of the hypotenuse side.

So,

Cos A = $\frac{adjacent}{hypotenuse}$

Cos A = $\frac{10}{12}$

Cos A = 0.833

Therefore, the exact value of cos A is 0.833.

Happy to help :)

What is smaller...<br> 3/10<br> 0.4<br> 35%

VMariaS [17]

Convert all of them in decimals

3 ÷ 10 = 0.3

0.4

35% ÷ 100 = 0.35

Order from least to greatest--

3/10, 35%, 0.4

3/10 is the smallest
