A calculator outputs an expression of 5.1E - 2. Which is an equivalent value? A 5.1 x 10-2
B -215
C 510
D 5.1 + 1020

The correct option is;

A. 5.1 × 10⁻²

Step-by-step explanation:

Given that the output of the calculator is 5.1E-2, which is in the scientific notation format, made use when the numerical values of the variable are very large or are very small, such that to completely write out such numbers may lead to occupying the majority of the available writing space

The number written as 5.1E-2 is the same as writing the number as 5.1 × 10⁻² which is also the same as 0.051.

what are ur choices?

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
