If (2^{a}=8) and (3^{b}=81), what is the value of (a^{b})?यदि (2^{a}=8) और (3^{b}=81), तो (a^{b}) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (81)(81)
From (2^{a}=2^{3}), (a=3), and from (3^{b}=3^{4}), (b=4), so (a^{b}=3^{4}=81). In exams, compare powers using equal bases.(2^{a}=2^{3}) से (a=3) और (3^{b}=3^{4}) से (b=4), इसलिए (a^{b}=3^{4}=81)। परीक्षा में घातों की तुलना समान आधार पर करें।
