What is the value of log0.5 16 (0.5 is the small bottom number)-4.00-0.251.512.41

Answer : -4.00

what is the value of  

We use log property to find the value

16 = 2*2*2*2 = 2^4

So we replace 16 by 2^4

As per log property we move exponent before log

0.5  can be written as 1/2 . 1/2 can be written as 2^-1

Now we apply change of base formula

Move the exponent -1 before log

log 2 will get cancelled

-4

-4.00 is the final answer

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
