the answer is g=+-(2sqrt(2))/(sqrt(3))

Explanation:

first add 8 to both side and to get rid of ^2, you have to do the opposite like nay other which is square root. and so you'll get g=sqrt(8/3) and you can simplify 8 to 2sqrt(2) and and 3 can't be simplified so you leave it alone and there you go

g=(+-2sqrt2)/(sqrt3)

Explanation:

Given: 3g^2-8=0.

Add 8 to both sides.

3g^2-color(red)cancelcolor(black)8+color(red)cancelcolor(black)8=0+8

3g^2=8

Divide by 3 on both sides.

(color(red)cancelcolor(black)3g^2)/(color(red)cancelcolor(black)3)=8/3

g^2=8/3

Square root both sides to get g.

g=+-sqrt(8/3)

=+-(sqrt8)/(sqrt3)

=(+-2sqrt2)/(sqrt3)
