How do I calculate this logarithmic expression?

Question

What I'm not sure about is the power of two above the logarithm. I just wanted to verify I'm calculating correctly

Do I do these steps...?

1 - Take absolute value of variable AL

2 - Take log base 10 of result 1

3 - take result 2 squared

4 - take result 3 multiply by variable b2

expression

Yes. Ps you can't take logs of negative numbers anyway :). – Chinny84 Feb 05 '14 at 02:18 — Chinny84, Feb 05 '14 at 02:18

Yes, this is correct. $\log^2x$ is short for $(\log x)^2$.

Yes.Your solution is $b_2(\mathrm{\log}_{10 }|AL|)^2$.
