what is the rational exponent form of this expression?

If you choose to fully simplify this expression, then the answer is b^3

If you just want to convert to rational exponent form, then the square root will be replaced with an exponent of 1/2. The rule is sqrt(x) = x^(1/2)

So,

sqrt(b^6) = (b^6)^(1/2)

which can be written as

note how the exponents 6 and 1/2 multiply to 3, which is why the fully simplified version is b^3

noncoplanar points are points that do not lie on the same line.

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60
