Write as a product: 25a2−0.01b10

Yakvenalex [24]

Answer:

We conclude that:

$25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)$

Step-by-step explanation:

Given the expression

$25a^2-0.01b^{10}$

Rewrite $25a^2-0.01b^{10}$ as $\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2$

$25a^2-0.01b^{10}=\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2$

Apply difference of two squares formulas:

$x^2-y^2=\left(x+y\right)\left(x-y\right)$

$\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2=\left(5a+\sqrt{0.01}b^5\right)\left(5a-\sqrt{0.01}b^5\right)$

$=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)$ ∵ $\sqrt{0.01}=0.1$ ,

Therefore, we conclude that:

$25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)$

Hans and Franz are two fitness fanatics. On a run from A to B, Hans runs half the way and walks the other half. Franz runs for h

snow_lady [41]

Answer :Hans

Here is an informal argument. Since Franz and Hans run
faster than they walk, Hans will go farther in the time that he runs
than in the equal time that he walks. Therefore he covers more
distance at a run than Franz does, since Fred covers equal distances
running and walking.

While both are walking or both are running, they will cover equal
distances. Therefore subtract this distance from the total distance.
The remaining distance is covered by Franz at a walk and by Hans at a
run, so Hans will finish first.
