(C) આપેલ સમીકરણ: ${\left( \frac{2}{3} \right)^{x + 2}} = {\left( \frac{3}{2} \right)^{2 - 2x}}$આપણે જાણીએ છીએ કે $\frac{3}{2} = {\left( \frac{2}{3} \right)^{-1}}$.આ કિંમત સમીકરણમાં મૂકતા: ${\left( \frac{2}{3} \right)^{x + 2}} = {\left( {\left( \frac{2}{3} \right)^{-1}} \right)^{2 - 2x}}$${\left( \frac{2}{3} \right)^{x + 2}} = {\left( \frac{2}{3} \right)^{-(2 - 2x)}}$${\left( \frac{2}{3} \right)^{x + 2}} = {\left( \frac{2}{3} \right)^{2x - 2}}$આધાર સમાન હોવાથી,ઘાતાંકોને સરખાવતા: $x + 2 = 2x - 2$$2 + 2 = 2x - x$$x = 4$

જો ${\left( \frac{2}{3} \right)^{x + 2}} = {\left( \frac{3}{2} \right)^{2 - 2x}}$ હોય,તો $x =$
