Can someone help me with this math (I'll give brainliest)

1/y^9= y^-9

1/m^15= m^-15

n^3=n^3

1/m^6=m^-6

n^4

w^12

1/32=2^-5

-6=(-6)^1

1^1

Step-by-step explanation:

Step-by-step explanation:

Use the exponent laws to identify which law to use.

1. y^-4 * y^-5 = y^-9

(add the exponents)

2. (m^-3)^5 = m^-3*5 = m^-15

(multiply the exponents)

3. n^-3 * n^6 = n^3

(add the exponents)

4. m^-12/m^-6 = m^-12-(-6) = m^-6

(subtract exponents)

5. (n^-2)^-2 = n^-2*-2 = n^4

(multiply the exponents)

6. w^5/w^-7 = w^5-(-7) = w^12

(subtract the exponents)

7. 2^-3 * 2^-2 = 2^-5

(add the exponents)

8. (-6)^4 * (-6)^-3 = -6^1

(add the exponents)

9. (4^-6)^0 = 4^-6*0 = 4^0 = 1

(multiply the exponents)

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

if you explain the the question more correctly i might be able to answer this better
