Calculate the product below and give your answer in

krok68 [10]

Answer:

$(1.5*10^{0})*(2.0*10^{-5})=3.0*10^{-5}$

Step-by-step explanation:

we know that

When multiply two numbers in scientific notation, multiply their coefficients and add their exponents.

we have

$(1.5*10^{0})*(2.0*10^{-5})=(1.5*2.0)*10^{(-5+0)}=3.0*10^{-5}$

therefore

$(1.5*10^{0})*(2.0*10^{-5})=3.0*10^{-5}$
