Which of the following demonstrates the commutative property across multiplication for 2×10×7

1 answer:

4 0

Commutative property basically states that u can " commute " ...move the numbers around

so the commutative property of 2 * 10 * 7 could be 7 * 2 * 10... or 10 * 7 * 2...or 10 * 2 * 7 or 2 * 7 * 10....I think u get what I mean

What is the recursive formula for 100, 80, 64, 51.2?

bonufazy [111]

From 100 to 80 is 8/10, so the recursive formula is

an=a(n-1)*1/8

an= a1*1/8(n-1)

an=a1*(n-1)/8

Simplify 4/(√5+ √2) - 3/(√5- √2)

MakcuM [25]

Step-by-step explanation:

$\frac{4}{ \sqrt{5} + \sqrt{2}} - \frac{3}{ \sqrt{5} - \sqrt{2} } = \\ = \frac{4( \sqrt{5} - \sqrt{2} ) - 3( \sqrt{5} + \sqrt{2} ) }{( \sqrt{5} + \sqrt{2} )\times ( \sqrt{5} - \sqrt{2} )} = \\ = \frac{4 \sqrt{5} - 4 \sqrt{2} - 3 \sqrt{5} - 3 \sqrt{2} }{5 - \sqrt{10} + \sqrt{10} - 2 } = \\ = \frac{ \sqrt{5} - 7 \sqrt{2} }{3}$
