Answer:

<u>3x^7</u>

y^z

Step-by-step explanation:

Any <u>non-zero</u> expression raised to the <u>power</u> of 0 equals 1.

<u>3x^3y^-1z^-1</u>   -->  <u>3x^3y^-1z^-1</u>   -->  <u>3</u><u>x^7</u><u>y^-1z^-1</u>

x^-4×1z^0              x^-4×1×1                     1×1

Any expression multiplied by 1 remains the same.

<u>3x^7y^-1z^-1</u>

        1

Any expression multiplied by 1 remains the same.

3x^7y^-1z^-1

Any expression raised to the <u>power</u> of -1 equals its <u>reciprocal</u>

3x^7× 1/y × 1/z

Calculate the <u>product</u>

<u>3x^7</u>

y^z

A line segment BK is an angle bisector of ΔABC. A line KM intersects side BC such, that BM = MK. Prove: KM ∥ AB.
weqwewe [10]

Answer:

∠BKM= ∠ABK

Therefore AB ║KM (∵ ∠BKM= ∠ABK  and lies between AB and KM and BK is the transversal line)

m∠MBK ≅ m∠BKM (Angles opposite to equal side of ΔBMK are equal)

Step-by-step explanation:

Given: BK is an angle bisector of Δ ABC. and line KM intersect BC such that, BM = MK

TO prove: KM ║AB

Now, As given in figure 1,

In Δ ABC, ∠ABK = ∠KBC (∵ BK is angle bisector)

Now in Δ BMK, ∠MBK = ∠BKM (∵ BM = MK and angles opposite to equal sides of a triangle are equal.)

Now ∵ ∠MBK = ∠BKM

and  ∠ABK = ∠KBM

∴ ∠BKM= ∠ABK

Therefore AB ║KM (∵ ∠BKM= ∠ABK and BK is the transversal line)

Hence proved.
