Answer:

Associative property

Step-by-step explanation:

<u>The given property is:</u>

A + (B + C) = (A + B) + C

which is called "associative property of addition".

Hence, this property is used in the given expression which is "rearranging the parenthesis does not affect the result."

$\rule[225]{225}{2}$

Hope this helped!

I'll let <em>h</em> = <em>ax</em>, so the limit is

$\displaystyle\lim_{h\to0}\frac{(x+h)^2-2(x+h)+1-(x^2-2x+1)}h$

i.e. the derivative of $x^2-2x+1$ .

Expand the numerator to see several terms that get eliminated:

$(x+h)^2-2(x+h)+1-(x^2-2x+1)=x^2+2xh+h^2-2x-2h+1-x^2+2x-1=2xh+h^2-2h$

So we have

$\displaystyle\lim_{h\to0}\frac{2xh+h^2-2h}h$

Since <em>h</em> ≠ 0 (because it is approaching 0 but never actually reaching 0), we can cancel the factor of <em>h</em> in both numerator and denominator, then plug in <em>h</em> = 0:

$\displaystyle\lim_{h\to0}(2x+h-2)=\boxed{2x-2}$

Step-by-step explanation:

Given

$= \frac{1.5 \times {10}^{4} \times 4.5 \times {10}^{3} }{2.5 \times 10 ^{2} } \\ = \frac{6.75 \times {10}^{4 + 3} }{2.5 \times {10}^{2} } \\ = \frac{6.75 \times {10}^{7} }{2.5 \times {10}^{2} } \\ = 2.7 \times {10}^{7 - 2} \\ = 2.7 \times {10}^{5}$

Hope it will help :)
