Answer: D
Step-by-step explanation:
From the equation given , ( -3)⁰(2x⁻¹y⁻¹)²
Recall :From the laws of indicies,
x⁰ = 1 ,and (xᵃ)ᵇ = xᵃ ˣ ᵇ = xᵃᵇ. and x⁻¹ = 1/ₓ
Therefore,
(-3)⁰ = 1,
( 2x⁻¹y⁻1 )² = 2²x⁻¹ ˣ ²y⁻¹ x ²
= 2²x⁻²y⁻²
=4x⁻²y⁻²
Now going by the law above, the expression will be
=4/ₓ²y²
So the answer is D
You have to divide 397 and 8.
Answer:
C
Step-by-step explanation:
there are 3 people who did 32 and there are 3 people who did 50 so it is the same number.
Consider the given statement:

We have to identify the property used in this statement.
1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that
. This property is not used in the given statement.
2. Commutative property of multiplication: Let 'a' and 'b' be two real numbers. This property states that
.
In the given statement,
This statement holds commutative property of multiplication as whether 2 is multiplied to
or
is multiplied to 2, the result is same.
So, Commutative property of multiplication is illustrated in this statement.
3. Inverse property of multiplication: A number 'a' is said to have an inverse '
' if
. This property is not used in the given statement.
4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that
. This property is not used in the given statement.
