Question

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

Answer 1

Step-by-step explanation:

$\frac{9 \times 10 {}^{ - 8} }{3 \times 10 {}^{ - 12} }$

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

$3 \times 10 {}^{ - 8 + 12} = 3 \times 10 {}^{4}$

The answer is

$3 \times 10 {}^{4}$

or

$30000$

Answer 2

Answer:

30000(thirty thousand) times larger

Step-by-step 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
