(a) an astronomer’s infrared telescope is able to detect radiation with a wavelength of ( 8.35 \times 10^{-4} ) meters. write this number in standard notation.
(square) meters
(b) the diameter of mars at its equator is approximately 6790 kilometers. write this number in scientific notation.
(square) kilometers

Explanation:

Step1: Convert scientific to standard form

$8.35 \times 10^{-4} = 0.000835$

Step2: Convert number to scientific notation

$6790 = 6.79 \times 10^{3}$

Answer:

(a) 0.000835 meters
(b) $6.79 \times 10^{3}$ kilometers
