Question

the diameter of the sun is 1.4 × 10 raise to power 9 M and the diameter of the Earth is 1.2756 × 10 raise to power 7 M show that the diameter of the sun is nearly hundred times the diameter of the earth

Answer 1

sun diameter =
$1.4 \times {10}^{9}$
earth diameter =
$1.2756 \times {10}^{7}$
sun diameter/earth diameter =
$\frac{1.4 \times {10}^{9} }{1.2756 \times {10}^{7} }$
=1.09 × 10^2
=109 ~100 times.

Answer 2

This is a simple question based on the basic concepts of multiplication,division and some of the rules of exponents.

So, what I did here was we just need to divide the sun's diameter by the earth's diameter. After doing so we will get that the diameter of the sun is nearly hundred times the diameter of the earth.

You should keep in mind that the answer we get in these type of questions are approximate. Even in the question, the word 'nearly' is given.
