Answer:
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
