Question

The Confederation Bridge connects News Brunswick to Prince Edward Island. The main part of the bridge rests on piers that form 43 segments. One segment is 8.2 x $10^{2}$ feet. What is the approximate length of the bridge in scientific notation?

Answer 1

Answer: $3.5$ × $10^{4}$

Step-by-step explanation:

Write an expression to represent the problem.

(8.2 × 10²) × 43

= (8.2 × 10²) x (4.3 x $10^{1}$)

Now, multiply.

(8.2 × 10²) x (4.3 x $10^{1}$)

= (8.2 x 4.3) x ($10^{2}$ x $10^{1}$)

= 35.26 x $(10)^{2+1}$

= 35.26 x 10³

= 3.526 x $10^{4}$
