answer: 5. -16r^7

9. 30t^6 v ^10

step-by-step explanation:

5. -16r⁷

7. 55w⁷x⁴

9. 30t⁶v¹⁰

step-by-step explanation:

according to the product-to-power exponential rule, whenever you multiply terms with exponents and coefficients, you add the exponents.

**i have a video that explains all six exponential rules. it is titled "six exponential procedures". i encourage you to watch the video and gain alot more knowledge from it, so you can better understand the concept.

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
