Question

27x² 108x²y 144xy² 64y²

Answer 1

the answer First, add 12 to both sides:

27x2=12

second divide both sides by 27: x over the power of 2 = 12/27

third reduce the fraction to lowest terms: x over the power of 2 =4/9

fourth take First, add 12 to both sides:

27

x

2

=

Second, divide both sides by 27:

x
