Answer:
135
Step-by-step explanation:
m^2 = 3
Cube m^2
(m^2)^3 = 3^3
m^(2*3) = 27
m^6 = 27
Now multiply by 5
5 * m^6 = 5*27
5 m^6 =135
-7√5
rewrite 20 as 2^2·5
factor 4 out of 20. negative ∛4(5)-√5
rewrite 4 and 2^2 negative ∛2^2·5-√5
pull terms out from under the radical
-3(2√5)√5
multiply 2 by -3
-6√5-√5
subtract √5 from -6√5
-7√5
the answer is -7√5
Answer:
⸻⸻⸻⸻⸻
Solving
2X + 3Y = 5.5
⸻⸻⸻⸻⸻
Simplifying
2X + 3Y = 5.5
⸻⸻⸻⸻⸻
<u>Solving for variable 'X'.
</u>
<u>
Move all terms containing X to the left, all other terms to the right.</u>
⸻⸻⸻⸻⸻
Add -3y to each side of the equation.
2x + 3y + -3y = 5.5 + -3y
⸻⸻⸻⸻⸻
Combine terms: 3y + -3y = 0.
2x + 0 = 5.5 + -3y
2x = 5.5 + -3y
⸻⸻⸻⸻⸻
Divide each side by 2.
x = 2.75 + -1.5y
⸻⸻⸻⸻⸻
Simplifying.
x = 2.75 + -1.5y
