Im not sure this is is right this is scientific notation (4.18x10^-4)(9x^-4) 4.18 x 9. 10^-4x10^-4 well we add the exponents =37.62 which gives us 10^8 37.62 is not in scientific notion so we moves the decimal to the left which gives us 3.762 we add 1 to the. the exponent which gives us 10^9 3.762 x10^9 is this right
