ROOTS AND CUBES<br> Can someone please help me answer all 4 following?

Alex Ar [27]

NOTES:

squared (²) means multiply that number by itself 2 times
cubed (³) means multiply that number by itself 3 times
square root (√) means 2 numbers multiplied by itself on the inside simplify to 1 of that number on the outside of the radical
cubed root (∛) means 3 numbers multiplied by itself on the inside simplify to 1 of that number on the outside of the radical

Answer: (C) 41

<u>Step-by-step explanation:</u>

$\quad 6^2+\sqrt[3]{125} \\= 6 \cdot 6+\sqrt[3]{5\cdot 5 \cdot 5}\\= 36 + 5\\= 41$

Answer: (C) 10

<u>Step-by-step explanation:</u>

$\bigg(\dfrac{7}{3}\times \sqrt[3]{27}-2\bigg)\times \dfrac{1}{5} + \sqrt{81}$

$=\bigg(\dfrac{7}{3}\times \sqrt[3]{3\cdot 3 \cdot 3}-2\bigg)\times \dfrac{1}{5} + \sqrt{9\cdot 9}$

$=\bigg(\dfrac{7}{3}\times3-2\bigg)\times \dfrac{1}{5}+9$

$=(7 - 2)\times \dfrac{1}{5}+9$

$=5 \times \dfrac{1}{5}+ 9$

$= 1 + 9$

$= 10$

***************************************************************************************

8² = 8 · 8 = 64 11² = 11 · 11 = 121

5³ = 5 · 5 · 5 = 125 3³ = 3 · 3 · 3 = 27

$\sqrt{1600}=\sqrt{40\cdot 40}=40$ $\sqrt[3]{64}=\sqrt[3]{4\cdot 4\cdot 4}=4$

$\sqrt{144}=\sqrt{12\cdot 12}=12$ $\sqrt[3]{8000}=\sqrt[3]{20\cdot 20\cdot 20}=20$

Solve the system of equation?<br>2x - 4y = 10<br>7x - y = 12

allsm [11]

Answer:

x = 1.153846153846154

y = -1.923076923076923

Step-by-step explanation:

Multiply 7x - y = 12 by -4 and then add it to 2x - 4y = 10

2x - 4y = 10

+(-4( 7x - y = 12))

-26x = -30

$\frac{-26x}{-26} = \frac{-30}{-26}$

x = 1.153846153846154

Then plug in x to get y.

2(1.153846153846154) - 4y = 10

2.307692307692308 - 4y = 10

-2.307692307692308 -2.307692307692308

-4y = 7.692307692307692

$\frac{-4y}{-4} = \frac{7.692307692307692}{-4}$

y = -1.923076923076923

What is (5!)! / 5! (fraction form)?

guajiro [1.7K]

Well, the numerator alone is

(5•4•3•2)! = 120 !

and the denominator alone is

5!= 120 .

So the value of the whole fraction is

119 !
