Answer:

a) True

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0$

Step-by-step explanation:

Step(i):-

Given that the definite integration

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha$

we know that the trigonometric formula

sin²∝+cos²∝ = 1

cos²∝ = 1-sin²∝

step(ii):-

Now the integration

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha = \int\limits^\pi _0 {(\sqrt{cos^{2} \alpha } } \, )d\alpha$

= $\int\limits^\pi _0 {cos\alpha } \, dx$

Now, Integrating

$= ( sin\alpha )_{0} ^{\pi }$

= sin π - sin 0

= 0-0

= 0

Final answer:-

$\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0$

Help I can’t get this ! Please help

Answer:

$\sqrt{2^5}$

Step-by-step explanation:

First, deal with the product of the two powers of 2 inside the parentheses.

The two factors are powers of 2, so add the exponents.

$(2^{\frac{1}{2}} \cdot 2^{\frac{3}{4}})^2 =$

$= (2^{\frac{1}{2} + \frac{3}{4}})^2$

You need a common denominator, 4, to add the fractions.

$= (2^{\frac{2}{4} + \frac{3}{4}})^2$

$= (2^{\frac{5}{4}})^2$

Now you have an exponent raised to an exponent. Multiply the exponents and reduce the fraction.

$= 2^{\frac{5}{4} \times 2}$

$= 2^{\frac{10}{4}}$

$= 2^{\frac{5}{2}}$

When a fraction is an exponent, the numerator is an exponent and the denominator is the index of the root. A denominator of 2 means a root index of 2 which means square root.

$= \sqrt{2^5}$
