Write the following exponential expressions as equivalent radical expressions.
a. 2^(1 /2)

So will be equivalent to in radical form

Step-by-step explanation:

We have given expression

We have to write this in radical form

We know that if any fraction is in exponential form then if we write this in radical form then in radical form the exponent come inverse of its number

So can be written in radical form as

So will be equivalent to in radical form

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°

about 168 miles
