What is the value of the expression all of 4.8 multiplied by 10 to the power 9 over all of 1.6 multiplied by 10 to the power 3

4.8(10^9)/(1.6(10^3))

Pertinent quotient rule for similar bases with exponents...

(a^b)/(a^c)=a^(b-c)  so what you really have is:

(4.8/1.6)(10^(9-3))

3(10^6)

3X10^6

You must find the surface of the block therefore 98187 dived by 5628 = 583m squared
