#color(red)(19.76 = 1.976*10^1#

Explanation:

Scientific notation is the way that electronic calculators easily handle very large numbers or very small numbers

The exponent of 10 is the number of places the decimal point must be shifted to give the number in long form.

A positive exponent tells us that the decimal point is shifted that number of places to the right.

A negative exponent tells us that the decimal point is shifted that number of places to the left.

In scientific notation, the digit term indicates the number of significant figures in the number.

We have the value #19.76#

For this value, we need to move decimal point 1 places to the right.

This means that the power of 10 will be positive 1.

#color(red)(19.76 = 1.976*10^1#
