First divide the coefficients:-
-18 / -12 = 3/2
a^-2 / a^-4 = a^2
b^-5 / b^-6 = b
so the expression simplifies to 3a^2b / 2
Answer:

Step-by-step explanation:
In the US, the given number is in standard form.
__
In the UK, "standard form" is what we refer to as "scientific notation" in the US. The number in standard form there is ...
3.160×10²
Answer:
AG = 4
AH = 21
EC = 12
CH = 5
HE = 7
Step-by-step explanation:
<u><em>The complete question is</em></u>
The diameters of circles A, C and E are 32 cm, 24 cm and 14 cm respectively.
Which of the following statements are true? Select all that apply.
•AG = 4
•GC = 10
•AH = 21
•EC = 12
•EH = 5
•CH = 5
•HE = 7
The picture of the question in the attached figure
<u><em>Verify each statement</em></u>
1) AG = 4
we know that

----> radius of circle A
----> radius of circle C
substitute

therefore
The statement is true
2) GC = 10
we know that
----> radius of circle C
therefore
The statement is false
3) AH = 21
we know that

we have
----> radius of circle A

----> radius of circle C
----> radius of circle E
so


therefore
The statement is true
4) EC = 12
we know that
----> radius of circle C
therefore
The statement is true
5) EH = 5
we know that
----> radius of circle E
therefore
The statement is false
6) CH = 5
we know that

----> radius of circle C
----> radius of circle E
so

therefore
The statement is true
7) HE = 7
we know that
----> radius of circle E
therefore
The statement is true
