Question

Need some help.

Answer 1

\[2/3x ^{2}=50\]

Answer 2

\[\frac{2}{3}x^2=50\qquad\text{or}\qquad \frac{2}{3x^2}=50\]

Answer 3

The first one.

Answer 4

multiply both sides by 3 and divide both sides by 2\[\frac{2}{3}x^2=50\]\[\downarrow\]\[x^2=\frac{50\times3}{2}\]

Answer 5

then to get it just X how do you do that?

Answer 6

next take the square root of both sides
\[x\pm=\sqrt\frac{50\times3}{2}\]

Answer 7

that is the kind of typo i usually make!

Answer 8

\[\pm x=\sqrt\frac{50\times3}{2}\]

Answer 9

lol

Answer 10

would you break 50 up to 25 and 2?

Answer 11

you can turn the fraction into a simple number
can you rewright it as a product of prime numbers ?

Answer 12

I have to get it to simplest form... \[x=5\sqrt{2*3\div2}\] would you multiple the 2*3 then divide by 2?

Answer 13

\[\frac{50\times3}{2}=\frac{25\times2\times3}{2}={5^2\times3}=75\]
\[\sqrt{\frac{50\times3}{2}}=5\sqrt{3}\]

Answer 14

\[x=\pm5\sqrt3\]
