Question

Compare 8 · 10^7 to 2 • 10^4. .A: 8. 10^7 is 4,000 times larger than 2 · 10^4.B: 8. 10^7 is 400 times larger than 2 · 10^4.C: 8. 10^7 is 40 times larger than 2.10^4.D: 8. 10^7 is 4 times larger than 2.10^4.

Answer 1

we need to compare 8x10^7 with 2x10^4. So we need to divide 8x10^7 between 2x10^4.

`(8*10^7)/(2*10^4)=4*10^(7-4)=4*10^3=4000`

Therefore 8x10^7 is 4000 times larger than 2x10^4

ANSWER

A: 8 · 10^7 is 4,000 times larger than 2 · 10^4.
