The simplification of expression [tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex] is [tex]x^{5}y^{2}[/tex].
SimplificationWhat is simplification?Finding a solution to a complicated calculation that may involve square roots, cube roots, plus and minus integers, division, multiplication, and other mathematical operations is typically referred to as simplification.
What is exponent?The number of times a number has been multiplied by itself is referred to as an exponent.
Rule of exponents:Rule of the product of powers: When multiplying like bases, add the powers together.
Rule of the quotient of powers: When splitting like bases, take the powers out.
Solution for the expression:The expression is given as
[tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]
Applying multiplication and product rule, one power of x will be reduced and 2 power of y will be reduced.
Thus, the the simplified equation will become [tex]x^{5}y^{2}[/tex].

The diagram shows two right-angled triangles. OAB
and OCD
Work out the length of BD. I
7 cm
4 cm
14 cm
Given:
The diagram shows two right-angled triangles OAB and OCD.
To find:
The length of BD.
Solution:
Let the length of BD is x.
In triangle OAB and OCD,
[tex]\angle AOB\cong \angle COD[/tex] (Common angle)
[tex]\angle ABO\cong \angle CDO[/tex] (Right angle)
[tex]\Delta OAB\sim OCD[/tex] (By AA property of similarity)
We know that, the corresponding sides of similar triangles are proportional. So,
[tex]\dfrac{AB}{CD}=\dfrac{OB}{OD}[/tex]
[tex]\dfrac{4}{7}=\dfrac{14}{14+x}[/tex]
[tex]4(14+x)=14(7)[/tex]
[tex]56+4x=98[/tex]
Subtracting 56 from both sides, we get
[tex]4x=98-56[/tex]
[tex]4x=42[/tex]
[tex]x=\dfrac{42}{4}[/tex]
[tex]x=10.5[/tex]
Therefore, the length of BD is 10.5 cm.

use the graph above. find the slope and the y-int, then give the equation of the line y=mx+b
Answer: y = 2x + 4
Step-by-step explanation:
By looking at the graph, we can use rise over run to figure out the slope:
[tex]\frac{rise}{run} = \frac{2}{1} = 2[/tex]
Next, to find the y-intercept, see the point where the line meets with the y-axis, which is at (0,4). Now, simply place those variables found into y=mx+b, where m is the slop and b is the y-intercept.
y = mx + b
y = 2x + 4
