The numbers as powers of 5 are 5^-1, 5^-2, 5^-3 and 5^0
<h3>How to rewrite the numbers as a power of 5?</h3>
The numbers are given as:
• 0.2
• 0.04
• 125^-1
• 15^0
<u>Number 1: 0.2</u>
Express as fraction
1/5
Apply the power rule of indices
5^-1
<u>Number 2: 0.04</u>
Express as fraction
1/25
Express 25 as 5^2
1/5^2
Apply the power rule of indices
5^-2
<u>Number 3: 125^-1</u>
Express as fraction
1/125
Express 125 as 5^3
1/5^3
Apply the power rule of indices
5^-3
<u>Number 4: 15^0</u>
Evaluate the exponent
15^0 = 1
Express 1 as 5^0
15^0 = 5^0
Hence, the numbers as a power of 5 are 5^-1, 5^-2, 5^-3 and 5^0

-40i is the answer.
Answer:
Step-by-step explanation:
First find the first radius
c=88cm
=2*22/7*r=88cm
=r=14cm
22/7 (pie as common)(R1^2+R2^2=637cm)
14^2+R2^2=637cm
196+R2^2=637cm
R2^2=637-196=441
R2=√441
R2=21
first radius =14cm
second radius =21cm
