43. log2(z+20) - log2(x +2) -log2r


Expert Answer

Step 1

Solving the logarithmic equation algebraically:

log2(x+20)- log2(x+2) = log2 (x+2) = log2 x

According to the logarithmic rule log x – logy = log (x/y)

Therefore, equation be written as:

Step 2

To calculate the value of x we solve the quadratic equation from x...
