- Multiplying exponents of the same base:

- Dividing exponents of the same base:

- Powering a power to a power:

- Converting a negative exponent to a positive one:

<h2>1.</h2>
Firstly, solve the outside exponent:

Next, convert the negative exponents into positive ones:

<u>Your final answer is
</u>
<h2>2.</h2>
For this, just divide:

Step-by-step explanation:
Answer:
FG = 9.7ft
Step-by-step explanation:
Find the diagram in the attachment.
The diagram is a right angled triangle since one of its angle is 90°
Using SOH CAH TOA to calculate the length FG which is the hypotenuse.
According to SOH
Sin∠G = Opposite/Hypotenuse
To get the ∠G,
∠F+∠H+∠G = 180°
18°+90°+∠G = 180°
∠G = 180°-108°
∠G = 72°
Sin72° = 9.2/FG
FG = 9.2/sin72°
FG = 9.67feet
FG = 9.7ft (to the nearest tenth of a foot)
