If ∠1 and ∠2 are equal, why are lines l and m are parallel.

rosijanka [135]

The answer is D, the alternate exterior angles theorem.

Alternate, because the two angles are on opposite sides of line t.
Exterior, because both angles are outside of the parallel lines.

Therefore, alternate exterior angles theorem.

Solve the equation with rational exponents. (x minus 1 )Superscript 2 divided by 3 Baseline equals 64

Katarina [22]

Answer:

$x=513 \Rightarrow S=\{513\}$

Step-by-step explanation:

1) Rewriting for the sake of clarity:

$(x-1)^{\frac{2}{3}}=64$

2) To solve it, we need to turn the rational exponent equal to 1 via exponent rule of product. Multiplying 2/3 by its reciprocal 3/2 we get 1, since this is an equality we need to do it on the other side.

$(x-1)^{\frac{2}{3}}=64\\\\((x-1)^{\frac{2}{3}}]^{\frac{3}{2}}=(64)^{\frac{3}{2}}\\(x-1)=\sqrt{64^{3}}\\x-1+1=512+1\\x=513$
