Question

How many times greater is 8×10 to the 4 power than 4×10 to the 5 power

Answer 1

8x10^4= 80,000
4x10^-5 = 0.00004

Answer 2

$\text{Hey there!}$

$\bf{8\times10^4\ = \ ?}\\\\\bf{4\times10^5\ = \ ?}$

$\bf{10^4 = 10\times10\times10\times10\rightarrow\huge\text{{10,000}}}$

$\boxed{\bf{8\times10,000 = 80,000}}$

$\bf{10^5=10\times10\times10\times10\times10\rightarrow\huge{\text{100,000}}}$

$\boxed{\bf{4\times100,000 = 400,000}}$

$\text{400,000 - 80,000 = 320,000}\\\\\\\bf{or} \dfrac{400,000}{80,000}=\dfrac{1}{2}=0.5$

$\boxed{\bf{It\ is}\dfrac{1}{2}\bf{times\ greater}}$
