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)`

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)`
