Question

Solve: log2^x + log2^5 = log2^20
x = ???

Answer 1

we have
\[\log_2 x+\log_2 5=\log_2 20\]
We know the log property of addition
\[\log_B A+\log_B C=\log_B {A\times C}\]

Answer 2

We'll use it here
\[\log_2 x+\log_2 5=\log_2 20\]
\[\log_2 5x=\log_2 20\]
Can you solve it from here @Kingjames1 ?
