Question

solve 3 x 10 power 8 metre per second X 300 second

Answer 1

Answer:

9 × 10^10m/s OR 9× 10 to the power 10 M/s

Answer 2

Concept:

The exponent rule is the product of two exponent terms with the same base raised to the sum of the exponents.

Given:

(3 x 10 power 8 meters per second) X (300 seconds)

Find:

We are asked to find the solve (3 x 10 power 8 meters per second) X (300 seconds).

Solution:

We have,

(3 x 10 power 8 meters per second) X (300 seconds)

Now,

Rewrite the given data,

i.e.

(3 x 10⁸ meters per second) × (3 × 100 seconds)

⇒

(3 x 10⁸ meters per second) × (3 × 10² seconds)

Now,

Using the exponent rule,

i.e.

xᵃ xᵇ = xᵃ⁺ᵇ

i.e.

(3 x 10⁸ meters per second) × (3 × 10² seconds)

We get,

(3 x 10⁸ ) × (3 × 10² )

We get,

9 x 10⁸⁺²

9  x 10¹⁰

Hence, the value (3 x 10 power 8 meters per second) X (300 seconds) is 9  x 10¹⁰.
