The answer is 1 cm = 1.6m. We know this because the scale model was 25 cm and the building was 40m. To simplify, our proportion is 40 meters /25 centimeters to x meters/1 centimeter. 40/25= 1.6, so we can say that x (the scale factor) is 1 cm to 1.6 m.
Answer:
Step-by-step explanation:
<h3>#7</h3>
- 5⁵(16²5³)³ = 5⁵(2⁴)³(5³)³ = 5⁵2¹²5⁹ = 5¹⁴2¹²
<h3>#8</h3>
- (8⁴5³/8⁵)² = (5³/8)² = (5³)²/(2³)² = 5⁶ / 2⁶
<h3>#9</h3>
- (5⁸3⁷/5⁴)¹⁰ = (5⁴3⁷)¹⁰ = (5⁴)¹⁰(3⁷)¹⁰ = 5⁴⁰3⁷⁰
<h3>#10</h3>
<u>Multiplying powers with same base:</u>

- Same base with powers added up
<u>Multiplying powers with same exponent but different base:</u>

- Same exponent with bases multiplied
You simply do 6x5x4x3x2x1 :)
90^6=531441000000
80^-4= 1/80^4= 1/4960000
For this, use negative power rule x^-a= 1/x^a
