Answer -

  • Given expression -

\frac{4 \sqrt{5} }{3 \sqrt{2} }  \\

<u>we're</u><u> </u><u>required</u><u> </u><u>to </u><u>rationalise</u><u> </u><u>the </u><u>expression</u><u> </u><u>!</u>

<u>therefore</u><u> </u><u>,</u><u> </u><u>we'll</u><u> </u><u>be </u><u>rationalising </u><u>the </u><u>denominator.</u>

\frac{4 \sqrt{5} }{3 \sqrt{2} }  \times  \frac{3 \sqrt{2} }{3 \sqrt{2} }  =  \frac{12 \sqrt{10} }{18}  \\  \\ \implies \:  \frac{\cancel6(2 \sqrt{10}) }{\cancel{18} } \\  \\ \implies \:  \frac{2 \sqrt{10} }{3}

hope this helps !

Here are the step for solving this:
1. 3y + 5 > 23
-5 -5
3y/3 > 18/3
y > 6

In words what you are doing is getting y by itself on one side. Subtract the 5 to undo the adding of 5 first. Then, divide both sides by 3.
