Question

pls help me in solving the 6 sum​

Answer 1

Answer:

1) a = 2, b = 1 and c = 2.

2) 9/245

Step-by-step explanation:

Find the factors of 2205.

=> 2205 = 3 * 5*3* 7*7 = 3² * 5¹ * 7²

Now 3² * 5¹ * 7² = 3ᵃ * 5ᵇ * 7ⁿ  (note: i replaced c with n as i donot have  

                                                  superscript c)

When bases are same powers are equal.  

So  a = 2, b = 1 and n(or c) = 2.

Now 3ᵃ * 5⁻ᵇ * 7⁻ⁿ = 3² * 5⁻¹ * 7⁻² = 9/5*7² = 9/245.
