(7x^3y^2)(4x^3y^2)<br><br><br>^=exponents<br>solve in scientific Notation

Hitman42 [59]

<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.

$(7x^3y^2)(4x^3y^2)=(7\cdot 4)x^{3+3}y^{2+2}=28x^6y^4\\\\=2.8\cdot 10^1x^6y^4$

_____

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
