Okay, so let's start by writing one over me as in negative log or a negative exponent. That's oland of eats and part of negative one. Or call that Ellen is log based e. So this is this equal to negative one since our E. R log based E cancels. And now for part B, we can write the square root the power of 1/2, and we see that our law based time and our base 10 cancels and we're left with 1/2.
