Answer 2

Given,

4.22X 6X = 18.3X

4./2)-(2")(3) = 18.(3x)2

Let 2X = P and 3M = GQ

Then, 4(2 - (2*)(3*) - 18(3 = 4P2- PO - 18q

4P2+8PQ 9PQ 1802= O

4P(P + 20) - 90(P +20) 0

(4P 90P +20) =0

(4P-9Q) = 0 and (P +20) = 0

Case 1- 4P 9Q

putting P 2* andQ = 3X

4.2X = 9.3x

(2.2x = (3) 3x

2X* = 3x+2

(2/3yx*2 =1 = (2/3°

x+20 »x = -2

Case 2:-P -2Q

Putting P = 2% and Q =3*

2X = -2.3x

But we know, exponential function can't bee

negative so,

2X -2.3x
