Step-by-step explanation:
12g=12(2/3g-1)+ 11
12g=24/3g-12+11
12g-24/3g=-1
12g-8g=-1
4g=-1
g=-1/4
When radicals (square roots) include variables, they are still simplified the same way. We just have to work with variables as well as numbers
1) Factor the radicand (the numbers/variables inside the square root). Factor the number into its prime factors and expand the variable(s).
2) Bring any factor listed twice in the radicand to the outside
21 rounded to the nearest 10 is 20 :)
