L = B + 105
H = L + 24.....H = B + 105 + 24 ...H = B + 129
H + L + B = 324
(B + 129) + (B + 105) + B = 324
3B + 234 = 324
3B = 324 - 234
3B = 90
B = 90/3
B = 30 <==Bart's marbles
L = B + 105
L = 30 + 105
L = 135 <=== Lisa's marbles
H = B + 129
H = 30 + 129
H = 159 <=== Homer's marbles

<h3>Simplifying an expression</h3>
From the question, we are to simplify the give expression
The given expression is
![y^{3}\sqrt[5]{32x^{4} } - 7\sqrt[5]{x^{4}y^{15} }](https://tex.z-dn.net/?f=y%5E%7B3%7D%5Csqrt%5B5%5D%7B32x%5E%7B4%7D%20%7D%20%20-%207%5Csqrt%5B5%5D%7Bx%5E%7B4%7Dy%5E%7B15%7D%20%20%7D)






11. 
Multiply both sides by 2


Multiply both sides by a power of 3/2







x = 4
Hence,
