Can someone help me with this : 4g = 8
ratelena [41]

Answer:

4g = 8

You would just have to divide 4 on both sides. The 4's would cancel out and now your left with 8÷4 = 2

Your answer would be

Papessa [141]

Answer

3^{7y} * 81^{8y} * 3^9  * 27^{-9y} = 3^{7y} * (3^4)^{8y} * 3^9  *(3^3)^{-9y}          

                                =3^{7y} * (3)^{32y} * 3^9  *(3)^{-27y}\\\\=3^{7y +32y +9 -27y}\\\\=3^{12y+9}

Tip :    

\frac{1}{27^{9y}}  = 27^{-9y} = (3^3)^{-9y} = 3^{-27y}
