Question

Find x if 2log5 + 1/4 log81 log3=logx

​

Answer 1

Answer:

x=225

Step-by-step explanation:

$logx = log {5}^{2} + log {81}^{ \frac{1}{4} } + log3 \\ logx = log25 + log3 + log3 \\ \\ where, \sqrt[4]{81} = 3,and \: loga + logb=log(ab) \\ \\ logx = log(25 \times 3 \times 3) \\ x = 225$

hope this helps you ☺️☺️
