ans is a) 16

let ? = x
as x^(4/3) * x^(5/3) = 32*128 = 2^12
x^3 = 2^4^3
x = 2^4
9 years agoHelpfull: Yes(6) No(2)
let ? be x,
x^(4/3)/32 = 128/x^(5/3)
x^(4/3) * x^(5/3) = 128*32

x^(4/3+5/3) = 64*2*32
x^3 = 64*64 = 4*4*4*4*4*4 = 16^3
so x = 16
hence solved

let ? = x
=>x^(4/3)/32 = 128/x^(5/3)
=>x^(4/3) * x^(5/3) = 2^12
=>x^3 = 2^12
=>x = 16.
SO WE CAN CONCLUDE THAT ?=16

let ? be x,
x^(4/3)/32 = 128/x^(5/3)
x^(4/3) * x^(5/3) = 128*32

x^(4/3+5/3) = 128*32
x^(9/3)= 128*32
X^3=16^3
so x = 16

ans is optn a
x^(4/3)*x^(5/3)=(128*32)
x^(3)=4096
x=3sqrrtof4096
x=16.

option a 16 is correct answer.

x^3=16^3
x=16
9 years agoHelpfull: Yes(0) No(0)
x^(4/3 +5/3)=32*128
x^3 =4096.
x=16

x*t=(3/4x)*(t+16)
1/4xt=12x
t=48

let ? be x . Therefore x ^ (4/3) / 32 = 128 / x ^ (5/3) . or x ^ (4/3 + 5/3 ) = 128 *32 or x ^ 3 = 8 * 8 * 8 * 8 or x =16
