Answer:
It is correct. The digits in the tenths and hundredths places are the same, but in the thousandths place, 9 is greater than 8
Step-by-step explanation:
Given
Required
Select the true statement
Analyzing both number base on the place value.
Tenth: 7 = 7
Hundredth: 3 = 3
Thousandth: 9 > 8
Hence, the statement is correct.
<em>Option B answers the question because 9 is greater than 8</em>
The complete factorized form for the given expression is
<u>Step-by-step explanation:</u>
Step 1: Given expression:
Step 2: Trying to factor as a Difference of Squares
Factoring
As we know the theory that the difference of two perfect squares, can be factored into (A+B) (A-B)
from this, when analysing, 81 is the square of 9, is the square of
. Hence, we can write the given expression as,
By using the theory, we get
Again, we can further factorise the term
is the square of
. Therefore, it can be expressed as below
Now, we can not factorise further the term . Because it will come as
(3 is not a square term). Thereby concluding that the complete factorisation for the given expression is
