Answer:
The required answer is
.
Step-by-step explanation:
Consider the provided information.
We need to find the cube root of the expression
.
![\sqrt[3]{81}=\sqrt[3]{27\times 3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B81%7D%3D%5Csqrt%5B3%5D%7B27%5Ctimes%203%7D)
Use the property: ![\sqrt[n]{ab} =\sqrt[n]{a}\times \sqrt[n]{b}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bab%7D%20%3D%5Csqrt%5Bn%5D%7Ba%7D%5Ctimes%20%5Csqrt%5Bn%5D%7Bb%7D)
![\sqrt[3]{81}=\sqrt[3]{27}\times \sqrt[3]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B81%7D%3D%5Csqrt%5B3%5D%7B27%7D%5Ctimes%20%5Csqrt%5B3%5D%7B3%7D)
![\sqrt[3]{81}=3 \sqrt[3]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B81%7D%3D3%20%5Csqrt%5B3%5D%7B3%7D)
Hence, the required answer is
.
Answer:yellow .
Step-by-step explanation: you’re moving over 2 to the right. Right is positive. Down is negative, and since you’re doing 2 to the right, and down 1, we have (2,-1)
Answer:
A= 4.5×10^11
B= 3.5×10^3
Step-by-step explanation:
A
(5×10^3)= 5000
(9×10^7)=90000000
multiply both of them
=450000000000 or 4.5×10^11
B
(7×10^5)=700000
(2×10^2)=200
700000÷200
3500 or 3.5×10^3

This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying
. This is the second line. Then, you could take the square of the
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
