Evaluate: $(3.2x^6y^3) \times (2.1x^2y^2)$ when $x = 1$ and $y = 0.5$.
Given:
$(3.2x^6y^3) \times (2.1x^2y^2)$
To do:
We have to evaluate $(3.2x^6y^3) \times (2.1x^2y^2)$ when $x = 1$ and $y = 0.5$.
Solution:
$(3.2x^6y^3) \times (2.1x^2y^2)=3.2 \times 2.1 \times x^{6+2} \times y^{3+2}$
$= 6.72x^8y^5$
$= 6.72 \times (1)^8 \times (0.5)^5$
$= 6.72 \times 1 \times 0.03125$
$= 0.21$
