Answer :
Kriste respone is wrong
Solution:
Given that,
Kristen was asked to write each of the numbers in the expression 80,000 x 25 using exponents
Her response was (8 x 10 to the power of 3) x 5 to the power of 2
No, the response of Kristen is wrong
Let us first understand about exponents
An exponent refers to the number of times a number is multiplied by itself
Given expression is:
[tex]80000 \times 25[/tex]
Here, 80000 has 4 zeros
Therefore, it can be raised as 10 power 4
[tex]80000 = 8 \times 10^4[/tex]
Thus the expression becomes:
[tex]80000 \times 25 = 8 \times 10^4 \times 25[/tex]
Also, 25 can be written as 5 power 2
[tex]80000 \times 25 = 8 \times 10^4 \times 5^2[/tex]
Thus given expression is written as (8 x 10 to the power 4) x 5 power to the power 2
Thus Kristen respone is wrong, because he has raised 10 to power 3
