2.144*10^7:3.2*10^4

6.70*10^2

Step-by-step explanation:

Change the 2.144 to standard form to obtain

2144 * (10^-3 * 10^7) and also change the 3.2 to 32 * 10^-1 * 10^4

= 32*10^3

2144 * 10^4/32*10^3. since the base are equal (base 10) take only one and subtract the exponent. (2nd law of indices)

2144/32 * 10^4-3

64.97 * 10^1

6.497*10^1 * 10^1

=6.497*10^2
