Question

(C) दिया गया है $3^{x-2} = 5$.दोनों पक्षों में $\log_{10}$ लेने पर:$(x-2) \log_{10} 3 = \log_{10} 5$चूंकि $\log_{10} 5 = \log_{10} (10/2) = \log_{10}

Vedclass · Accepted Answer

$3 \frac{22187}{47710}$

Vedclass · Answer

(C) दिया गया है $3^{x-2} = 5$.दोनों पक्षों में $\log_{10}$ लेने पर:$(x-2) \log_{10} 3 = \log_{10} 5$चूंकि $\log_{10} 5 = \log_{10} (10/2) = \log_{10} 10 - \log_{10} 2 = 1 - 0.30103 = 0.69897$.अतः,$(x-2) (0.4771) = 0.69897$.$x-2 = \frac{0.69897}{0.4771} = 1.465038...$$x = 2 + 1.465038 = 3.465038$.भिन्न की गणना करने पर: $3 \frac{22187}{47710} = 3 + \frac{22187}{47710} \approx 3 + 0.465038 = 3.465038$.अतः,$x = 3 \frac{22187}{47710}$.

यदि $3^{x-2}=5$ और $\log_{10} 2=0.30103, \log_{10} 3=0.4771$ है,तो $x=$
