Question

Express the following numbers in standard form-

a) 0.000035
b) 4050000

Answer 1

1) 0.000035 = 3.5 x 10 raised to power -5.

2) 4050000 = 4.05 x 10 raised to power 6.

Answer 2

Answer:

The standard form of given numbers are $3.5\times 10^{-5}$ and $4.05\times 10^6$.

Step-by-step explanation:

We use the standard form of number to write a very larger number in a short form. The number is represented as $a\times 10^n$, we 0<a<10. For example:

$2000=2\times 1000=2\times 10^3$

a)$0.000035=3.5\times \frac{1}{100000}=3.5\times 10^{-5}$

b)$4050000=4.05\times 1000000=4.05\times 10^6$

Therefore the standard form of given numbers are $3.5\times 10^{-5}$ and $4.05\times 10^6$.
