#4.5xx10^(-2)Nm#

Explanation:

#(1.5xx10^6 N)(3.0xx10^-8 m)#

= #(1.5xx3.0)xx(10^6xx10^(-8))Nm#

= #4.5xx10^(6+(-8))Nm#

= #4.5xx10^(-2)Nm#

When a number is written in scientific notation, it is written in the form #axx10^n#, where #1<=a<10#, in other words #a# is just in unit digits and decimals but no tens or higher and #n# is an integer.

As #4.5xx10^(-2)Nm# is already in this form, this is the desired result.
