Write the values in the boxes that make the statement true

nikklg [1K]

Answer:

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$

Step-by-step explanation:

<u>Given</u>

$\frac{5}{3}xz^a*bx^cy^dz^2 = 15x^7z^{10}$

<u>Simplify</u>

$\frac{5}{3}b*x^{1+c}z^{a+2}y^d = 15x^7z^{10}y^0$

Compare left and right sides and

<u>Find b:</u>

<u /> $\frac{5}{3}$ b = 15 ⇒ b = 15*3/5 = 9

<u>Find c:</u>

1 + c = 7 ⇒ c = 7 - 1 = 6

<u>Find a:</u>

a + 2 = 10 ⇒ a = 10 - 2 = 8

<u>Find d:</u>

d = 0

<u>Solution is:</u>

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$
