Question

what is the number of significant figures in (3.50+450)×10^5

Answer 1

Answer:

The answer is 3

Explanation:

The explanation is that

After adding 453.5 comes then as we know addition rules of error so it has three significant figures

Answer 2

Answer:

The number of significant figure is 45350000.

Explanation:

Given,(3.50+450)×10^5

We want to simplify the expression.

So,

$(3.50 + 450) \times {10}^{5}$

We are adding 3.50 and 450,

$= 453.50 \times {10}^{5}$

We are removing decimal,

$= \frac{45350}{100} \times {10}^{5} \\ = \frac{45350}{100} \times 100000 \\ = 45350 \times 1000 \\ = 45350000$

Therefore the number of significant figure is 45350000.

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
