If (3^a=9) and (2^b=8), what is the value of (a+b)?यदि (3^a=9) और (2^b=8), तो (a+b) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (,5,)(,5,)
From (9=3^2), (a=2), and from (8=2^3), (b=3), so (a+b=5). In exams, remembering small powers gives faster solutions.(9=3^2) से (a=2) और (8=2^3) से (b=3), इसलिए (a+b=5)। परीक्षा में छोटे powers को याद रखना तेज समाधान देता है।
