56)E 57)E
Adım adım açıklama:
56) [tex]2^{5} =32\\[/tex]
[tex](2^{2})^{x} =5\\\\2^{2x} =5[/tex]
Her iki tarafı 5/2 üstünü alırsak 32 üzeri x ulaşmış oluruz.
[tex](2^{2x})^{\frac{5}{2} } =5^{\frac{5}{2}} \\\\32^{x} = 5^{2+\frac{1}{2} } \\\\32^{x} = 5^{2} .5^{\frac{1}{2} }\\\\32^{x} = 25\sqrt{5}[/tex]
57) [tex]5^{2} =25[/tex] , [tex]5^{3} =125[/tex]
[tex]125^{\frac{3x-4}{2}} =25^{\frac{4x+2}{3}}\\\\5^{\frac{3(3x-4)}{2}} =5^{\frac{2.(4x+2)}{3}}[/tex]
[tex]\frac{3.(3x-4)}{2} =\frac{2.(4x+2)}{3} \\\\\frac{9x-12}{2} =\frac{8x+4}{3}[/tex]
İçler dışlar çarpımı yaparız.
3.(9x-12)=2.(8x+4)
27x-36=16x+8
27x-16x=8+36
11x=44 => Her iki tarafı 11'e böleriz.
x=4
