Final Answer :
A
Explanation :
The expression log4[x5(x+6)2]\log _ { 4 } \left[ x ^ { 5 } ( x + 6 ) ^ { 2 } \right]log4[x5(x+6)2] can be expanded using the properties of logarithms as follows: the logarithm of a product is the sum of the logarithms ( logb(mn)=logb(m)+logb(n)\log_b(mn) = \log_b(m) + \log_b(n)logb(mn)=logb(m)+logb(n) ), and the logarithm of a power is the exponent times the logarithm ( logb(mn)=nlogb(m)\log_b(m^n) = n \log_b(m)logb(mn)=nlogb(m) ). Therefore, the expression expands to 5log4x+2log4(x+6)5 \log _ { 4 } x + 2 \log _ { 4 } ( x + 6 )5log4x+2log4(x+6) .
