2. In this lesson, you are expected to:
• Describe the exponent and the base
in a number expressed in exponential
notation.
• Give the value of numbers expressed
in exponential notation
3. Amaya was asked to express the
given numbers 3 x 3 x 3 x 3; 3
raised to the fourth power; and 3
with an exponent of four into
shorter number or exponential
number.
How will she write it?
What do we call the number?
What do we call each part of the
saidnumber?
4. Here’s how we solve the problem.
1. The expression 3 x 3 x 3 x 3
can be expressed as 34, same
through as 3 raised to four can
be expressed as 34 and 3
with an exponent of 4 as 34.
