Answer:

D) 8g^{6} h^{4} k^{12} -h^{25}k^{15}

Step-by-step explanation:

You have to use the laws of exponents to solve this:

Power of a Power: (a^{m} )^{n} = a^{mn}. In this case, (4g^{3} h^{2} k^{4} )^{3}, all of the numbers in the parenthesis need to be multiplied to the power of 3: 4^{3} g^{9} h^{6} k^{12}.

Quotient of Powers: \frac{a^{m} }{a^{n} } = a^{m-n}. In this case, \frac{4^{3} g^{9} h^{6} k^{12}}{8g^{3} h^{2} }, all of the exponents need to be subtracted (but the 4³ (64) and 8 need to be divided): 8g^{6} h^{4} k^{12}.

Use the Power of a Power again for the expression at the right: (h^{5} k^{3} )^{5}. You get: h^{25} k^{15}. Keep the subtraction/negative sign where it is.

Together, you get: 8g^{6} h^{4} k^{12} -h^{25}k^{15}.

Hope it helps!

A 36 ft tree casts a 9 ft shadow at the same time a building casts a 15 ft shadow. How tall is the building?
mote1985 [20]

Answer: The height of the tree is  27f t

Step-by-step explanation: We can set up a proportion comparing the height of each object to the length of the shadow.

h/s

h/15=18/10

Cross multiply

10.h= 18*15

10h=270

Use the multiplicative Inverse

10 h/ 10 = <em><u>270 /10 =27</u></em>
