Answer:
(-30000) · ([tex]\frac{2}{1000\\}[/tex]) = -60
Step-by-step explanation:
Base: (-3 · 10⁴) · (2 · 10⁻³)
Simplify the power terms. A make a negative exponent positive, flip it over the fraction bar, it works both ways: (-3 · 10000) · ([tex]\frac{2}{10^{3} }[/tex])
(-3 · 10000) · ([tex]\frac{2}{1000}[/tex])
(-30000) · (0.002)
= -60
