Question: Simplify and express each of the following in exponential form: \({2^0} + {3^0} + {4^0}\)...
Simplify and express each of the following in exponential form:
20+30+40
Solution
To write the given expression in the exponential form, first simplify the expression by simplifying each of the terms with the help of the exponential property a0=1. Then the obtained result can be expressed in the required exponential form by using another exponential property a=a1 .
Complete step by step solution:
If a number or any term is multiplied with itself for some number of times; then the expression which represents this repeated multiplication is called a power. For example, the repeated multiplication of 3 for two times can be shown as, 3×3=32. The digit 3 is called the base and the number 2 is called the exponent.
The given expression is,
20+30+40
To simplify and express the above expression in exponential form, use the exponent formula a0=1 .
The term 20 can be written by using the property a0=1 as,
20=1
The term 20can be written by using the property a0=1 as,
30=1
The term 20 can be written by using the property a0=1 as,
40=1
Substitute 1 for 2 0 , 1 for 3 0 and 1 for 4 0 in the given expression 20+30+40
and simplify.
20+30+40=1+1+1 =3
Thus, the required simplified value of the given expression is 3.
Write the simplified value 3 in exponential form by using the exponential formula a=a1
.3=31
Hence, the required exponential form of the simplified value of the given expression is 31.
Note:
In order to find the exponential form of the given expression we need to use the properties of exponentials that is, a0=1 and a=a1 . These are the necessary properties which should be used to simplify the given expression.
