Question

A lightening flash has a luminance of about 70,000,000,000 cd/m2. Write the luminance in engineering notation.

Answer 1

Answer: I’m not sure but I think it is:
`7 * 10^(10) (cd)/(m^(2))`. Hope this helps!

Answer 2

The luminance of a lightning flash, given as 70,000,000,000 cd/m2, is expressed in engineering notation as 70 x 10^9 cd/m2.

Step-by-step explanation:

To express the luminance of a lightning flash, which is about 70,000,000,000 cd/m², in engineering notation, we recognize that engineering notation is similar to scientific notation but uses powers of ten that are multiples of three. The value 70,000,000,000 cd/m² in engineering notation can be written as 70 x 10¹ cd/m², because 70,000,000,000 is the same as 70 billion, or 70 times 10 to the power of 9.
