Question

How many time larger is 9x10^-8 than 3x10^-12

Answer 1

30000(thirty thousand) times larger

Explanation:

9×10⁸ is the same as 900000000

3×10-¹² is the same as 0.000000000003

(9×10⁸)÷(3×10-¹²)

9÷3=3

10⁸÷10-¹²=10⁴

3×10⁴ which is 30000

Answer 2

Explanation:

`\frac{9 * 10 {}^( - 8) }{3 * 10 {}^( - 12) }`

Apply Quoteint of Powers. Divide the intergers. serpately.

Note that Quotient of Powers is

`\frac{a {}^(x) }{a {}^(y) } = a {}^(x - y)`

So the answer is

`3 * 10 {}^( - 8 + 12) = 3 * 10 {}^(4)`

The answer is

`3 * 10 {}^(4)`

or

`30000`
