Answer:
C
Step-by-step explanation:
Calculate AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 1, - 3) and (x₂, y₂ ) = B(11, - 8), thus
AB =
=
= = = 13 → C
Answer:
The answer is B
Step-by-step explanation:
This is because when you distribute the -4 to 9^6 and 7^-24 you will get 9^-24 and 7^36. Then, you can move the 7^-24 to the denominator because of the negative exponent rule.
PS: ^ means to the power of
The correct simplification will be: (b) ab²
Here we will use the property of exponents for division of two exponential terms with same bases. The original property is :
It means if the bases are same , then we will just subtract the exponents while dividing two terms.
Using this property:
and
So,
