Question

8*10^3 is how many times as large as 4*10^2

Answer 1

To find this, one can find how much each individual part is greater. 8 is 2 times greater then four and 10^3 is 10 times greater then 10^2. 10 * 2 is 20, so 8*10^3 is 20 times larger. 

Answer 2

8 * 10³  is 20 times larger than 4 * 10² .

What are Exponents ?

Exponents tells us about the base being raise by a power.

Exponents are written on superscript of the number.

The two expressions given are

8 * 10³  and 4 * 10²

to find  how many times 8 * 10³ is larger than 4 * 10²

x = ( 8 * 10³ )/(4 * 10²)

By exponent rule

$\rm x = 2 * 10 ^{3-2}$

x = 2 * 10 = 20

Therefore Expression 1 is 20 times larger than Expression 2
