Answer 1

$6.0014 * 10^10

Explanation:

a) To find the amount in Canadian dollars, we need to multiply the amount in U.S. dollars by the exchange rate.

Given:

- Assets worth $46.6 billion U.S.

- Each U.S. dollar was worth about $1.29 Canadian.

To convert the amount in U.S. dollars to Canadian dollars, we can multiply $46.6 billion by the exchange rate of $1.29 Canadian per U.S. dollar:

$46.6 billion U.S. * $1.29 Canadian/U.S. dollar = $60.014 billion Canadian

Therefore, the amount of $46.6 billion U.S. is worth $60.014 billion Canadian.

b) To express the amount in Canadian dollars using scientific notation, we can rewrite $60.014 billion as a number between 1 and 10 multiplied by a power of 10.

$60.014 billion = $6.0014 * 10^10 Canadian

Therefore, the amount of $46.6 billion U.S. is equivalent to $6.0014 * 10^10 Canadian when expressed in scientific notation.
