D4

Answer:

A. 1

Read Explanation:

നൽകിയിരിക്കുന്ന വ്യഞ്ജകം:

(34)5×712(72)6×910\frac{(3^4)^5 \times 7^{12}}{(7^2)^6 \times 9^{10}}

പവർ നിയമം ഉപയോഗിക്കാം

(am)n=amn( a^m )^n = a^{mn}
(34)5=320(3^4)^5 = 3^{20}
(72)6=712(7^2)^6 = 7^{12}

320×712712×910\frac{3^{20} \times 7^{12}}{7^{12} \times 9^{10}}
7^{12} cancel ചെയ്യാം


=320910= \frac{3^{20}}{9^{10}}
9=329 = 3^2

910=(32)10=3209^{10} = (3^2)^{10} = 3^{20}

ഇപ്പോൾ,

320320=1\frac{3^{20}}{3^{20}} = 1
