1 answer:
<h3>Answer:</h3>
(2.8×10¹)x⁶y⁴
<h3>Step-by-step explanation:</h3>Multiplication can be done in the usual way, then the number converted to scientific notation. Scientific notation does not apply to the variables.
_____
If you write the numbers in scientific notation to start, then do the multiplication, the effect is virtually the same: an adjustment is needed in the product to get it back to scientific notation.
(7)(4) = (7×10⁰)(4×10⁰) = 7·4×10⁰⁺⁰ = 28×10⁰ = 2.8×10¹
