There are four rules to multiplying eksponen:
a. The
first rule:
When exponen are same for both base
#’s, multiply bases and keep same
exponen. If we have the number a
and b, and the exponen n same to both number
= (we simplipy a times b and keep the same
exponen n)
For example:
= If 3 is a, 4 is b, and 5 is n,
base on first rule , simplipy 3 times 4
and keep the same exponen 5
=
Before we go on, remember:
If we see something raised to the second
power, we say it the square and if raised to the third power, we say it cube.
for example:
=
=
=576
Six square times four square is equals to
six time four square is equals to twenty four
square is equals to twenty four times
twenty four is equals to five hundred seventy six.
b. Rule
# 2
This rule is just same for the first but
divide instead of multiply.
=[ a and b is base number and n is exponen. We
divide the base number and keep the same
exponen n.
For example:
= [
=
= 2x 2x2
= 8
six cube divide by three cube is equals
to six divide by three cube. It’s equals to two
cube. Two cube is two times two times
two. The result is eight.
c. Rule
#3
In this third rule, the base number
is one and the exponens are m and n. To solve it, we can multiply the exponen.
=
For
example:
= Two cube square. Muliply the exponen 3
and 2.
= We find two to the six power. It is same to two times
= 2x2x2x2x2x2 two times two times two times two times
two.
= 64 we
find sixty four.
d. Rule
# 4
If there are different exponents and same
base numbers, so add the exponents and use the common base.
If we given a to the m power times
a to the n power, it is equals to a to the m plus n power.
=
For example:
= we keep the base two and add the
exponents.
=
= 2x2x2x2x2x2x2
=
= 2x2x2x2x2x2x2
= 128
