scientific notation.
(1.5 x 10°) x (2.0 x 10-5) = ?

Answer 1

7.8 x 10^7

Explanation:

do i have to explain

Answer 2

`(1.5*10^(0))*(2.0*10^(-5))=3.0*10^(-5)`

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)`
