Answer: 143 packages
Step-by-step explanation: You divide 9,438 by 66
The answer is
![\sqrt[3]{ \frac{ a^{6} b^{9} }{-64} } = \frac{ \sqrt[3]{a^{6} b^{9}} }{ \sqrt[3]{-64} } = \frac{ \sqrt[3]{a^{6}} * \sqrt[3]{ b^{9}} }{ \sqrt[3]{-64}}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B%20a%5E%7B6%7D%20b%5E%7B9%7D%20%20%7D%7B-64%7D%20%7D%20%3D%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7Ba%5E%7B6%7D%20b%5E%7B9%7D%7D%20%7D%7B%20%20%5Csqrt%5B3%5D%7B-64%7D%20%20%7D%20%3D%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7Ba%5E%7B6%7D%7D%20%2A%20%5Csqrt%5B3%5D%7B%20b%5E%7B9%7D%7D%20%7D%7B%20%20%5Csqrt%5B3%5D%7B-64%7D%7D%20)
Since (xᵃ)ᵇ = xᵃ*ᵇ, then:
a⁶ = (a²)³
b⁹ = (b³)³
Also: 64 = 4³
![\frac{ \sqrt[3]{a^{6}} * \sqrt[3]{ b^{9}} }{ \sqrt[3]{-64}}= \frac{ \sqrt[3]{( a^{2})^{3} }*\sqrt[3]{( b^{3})^{3} } }{\sqrt[3]{( -4)^{3} }} = \frac{ a^{2} * b^{3} }{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B%20%5Csqrt%5B3%5D%7Ba%5E%7B6%7D%7D%20%2A%20%5Csqrt%5B3%5D%7B%20b%5E%7B9%7D%7D%20%7D%7B%20%5Csqrt%5B3%5D%7B-64%7D%7D%3D%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B%28%20a%5E%7B2%7D%29%5E%7B3%7D%20%7D%2A%5Csqrt%5B3%5D%7B%28%20b%5E%7B3%7D%29%5E%7B3%7D%20%7D%20%7D%7B%5Csqrt%5B3%5D%7B%28%20-4%29%5E%7B3%7D%20%7D%7D%20%3D%20%5Cfrac%7B%20a%5E%7B2%7D%20%2A%20b%5E%7B3%7D%20%7D%7B-4%7D%20)
Answer:
645/100 = 129/20 or 6.45
645/50 = 129/10 or 12.9
48.6/30 = 1.62
48 divided by x = 48.6/x
Step-by-step explanation:
645/100
Factor the number:
= 5*129/100
Factor the number:
= 5*129/5*20
Cancel the common factor:
= 129/20
645/50
Factor the number:
5*129/50
Factor the number:
5*129 / 5*10
Cancel the common factor:
= 129/10
48.6/30
Write the problem in long division format
Multiply the quotient digit (1) by the divisor (30)
Subtract 30 from 48
Add a decimal and bring down the next number
Divide 186 by 30 to get 6
Continue...A few steps later...
Subtract 60 from 60
Solution is 1.62
48.6/x
Re-write division as a fraction:
48.6/x
