I’m not sure about the answer to these 2 questions, pls provide a step by step explanation if possible, it’s ok if not

2*10^4= 20000

Step-by-step explanation:

Divide 8.4 by 4.2 and multiply that by 10^7 divided by 10^3

8.4/4.2 = 2

10^7/10^3 =

10^4

Multiply them together:

2*10^4 = 20000

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
