2ab (cube root(192ab^2)) - 5 (cube root(81a^4b^5))
First simplify the radicals.
cubert (192) = (4*4*4*3) = 4cubert(3)
cubert (81) = (3*3*3*3) = 3cubert(3)
8ab cubert(3ab^2) - 15ab cubert(3ab^2)
- 7ab cubert (3ab^2)
Option 4

2ab( \sqrt[3]{192ab^2} )-5( \sqrt[3]{81a^4b^5} )=2ab( \sqrt[3]{4^3*3*ab^2} )-5( \sqrt[3]{3^3*3*a^4b^5} )= \\ \\ =2ab(4 \sqrt[3]{3ab^2} )-5( 3ab\sqrt[3]{3ab^2} )=8ab(\sqrt[3]{3ab^2} )- 15ab(\sqrt[3]{3ab^2} )= \\ \\ =(8ab-15ab)(\sqrt[3]{3ab^2})=-7ab(\sqrt[3]{3ab^2})

Simplify. -10m+2m^4-13m-20m^4
Ulleksa [173]
First one:

you can add -10m and -13m but you can't add -10m and 2m^4 becuase the powers aren't the same so

when adding the like terms
look at the:
powers, (x^3 adds with x^3)
placehloder letter (x adds with x and y adds with y and so on)

-10m+2m^4-13m-20m^4
powers: m^1 and M^4
placeholders: all m


add
-10m-13m+2m^4-20m^4
-23m-18m^4




second one:
when multiplying exponents, you add with like
so if you multipliy
x^2yz^3 times x^4y^2z^2 thne you would get x^6y^3z^5
when multiply with coeficients
2x^2yz^3 times 4x^4y^2z^2=8x^6y^3z^5
so using associative property a(bc)=(ab)c
2/3 times p^4 times y^3 times y^4 times s^5 times 6 times p^2 times s^3
group like terms

(2/3 times 6) times (p^4 times p^2) times (y^3 times y^4) times (s^5 times s^3)
(4) times (p^6) times (y^7) times (s^8)
4p^6y^7s^8

I'm really confused about this but how do you solve problems with finding the slope of a line pls I need help with a whole front
faust18 [17]
To find the slope you use the slope formula y2-y1 / x2-x1. So use two point on the line we will make ours (1,2) and (3,4). Substitute to make 4-2 / 3-1 = 1/1 so using the rise over run method. The line rises up one and runs by one. The slash mark means divide, it's easiest in a fraction.

Also if you come across the equation y=mx+b, m is the slope and b is the y-intercept, this is called slope intercept formula.

What are the coordinates of the imageof point A (2, -7) under the transalition (x,y) (x- 3, y 5)
jenyasd209 [6]

Answer:

The coordinates of the image of point A (2, -7) are A'(-1,-2).

Step-by-step explanation:

Note: The sign is missing between y and 5 in the rule of transitional.

Consider the rule of translation is

(x,y)\Rightarrow (x-3,y+5)

We need to find the image of point A (2, -7).

Substitute x=2 and y=-7 in the above rule.

A(2,-7)\Rightarrow A'(2-3,-7+5)

A(2,-7)\Rightarrow A'(-1,-2)

Therefore, the coordinates of the image of point A (2, -7) are A'(-1,-2).
