That's a good start!
i think what i have to do next is multiply the fraction by is denominator?
yes
which is \[\sqrt{7}\]
correct keep going
i know that the denominator will turn into 7 but the numerator
\[\huge~\frac{ \sqrt{20} \times \sqrt{7}}{ \sqrt{7}\times \sqrt{7} }\]
20 x 7 =?
140
good so the answer is....?
i'm guessing you want me to factor 140 in that case it 35*4
since you can take the squareroot of 4 it's 2 so the answer is \[2\sqrt{35}\]
over 7
is that correct?
Yes, but write \(\Large \frac{2\sqrt{35}}{7}\)
yea thanks :)
You're welcome! :)
