Answer 2

The value required value is 15.1

Step-by-step explanation:

Consider the provided expression.

$7^{2.3} \times 49^{4.7} \times 63^{3.4}\times81^{5.85} = 63^?$

Rewrite the equation as shown:

$7^{2.3} \times (7\times7)^{4.7} \times (7\times9)^{3.4}\times(9\times9)^{5.85} = 63^?$

$7^{2.3} \times 7^{4.7+4.7} \times 7^{3.4}\times9^{3.4}\times9^{5.85+5.85}= 63^?$

$7^{2.3} \times 7^{9.4} \times 7^{3.4}\times9^{3.4}\times9^{11.7}= 63^?$

$7^{(2.3+9.4+3.4)}\times9^{(3.4+11.7)}= 63^?$

$7^{15.1}\times9^{15.1}= 63^?$

$63^{15.1}= 63^?$

Hence, the value required value is 15.1
