The Planck constant can be written as 6.626070 x 10-34 Choose the correct exponential notation for Planck's constant
expressed with three significant figures.
a 6.62 x 1034 J. S
b 6.63 x 10-34 j. s
C 6.02 x 1034 J. S

The correct exponential notation for Planck's constant is.

Explanation:

Given that,

Planck constant =

We need to find the correct exponential notation for Planck's constant

According to the given options,

In option (a) :

The given value in option is

In this option, the given value is in three significant figures but the negative sign is missing in the exponential term.

So, this is the incorrect option.

In option (b) :

The given value in question is

We write the value of the Planck constant with three significant figures.

The Planck constant with three significant figures will be

So, this is the correct option.

In option (c) :

The given value is

In this option, the given value is in three significant figures but this value is not the Planck constant value.

So, this is the incorrect option.

Hence, the correct exponential notation for Planck's constant is.

The correct option is (b).
