Question

(3x10^(-15)) × (3x10^(3))

Answer 1

`(3 * 10)^( - 12) = (1)/((3 * 10)^(12) )`

Explanation:

When we multiply two equal values with different power, we sum the two powers.

Negative power is equ to 1 over the value with positive power:

`(3 * 10)^( - 15) * (3 * 10) ^(3) = \\ (3 * 10) ^( - 15 + 3) = (3 * 10) ^( - 12) = \\ = \frac{1}{ {(3 * 10)}^(12) }`
