Answer:

Choice B is correct.

Step-by-step explanation:

We have given the expression.

(2⁵)⁻²

We have to simplify it.

We know that :

(a²)³=a⁶

So, above expression is :

2⁻¹⁰

As we also know that:

a⁻¹ = 1/a

So,the expression is:

1/2¹⁰

As 2¹⁰ = 1024

So, 1/2¹⁰ = 1/1024

1/1024 is the simplification.

Answer:

The correct answer is option 3

2⁻¹⁰ and 1/1024

Step-by-step explanation:

Points to remember

1). ( xᵃ)ᵇ = xᵇ

2).  x⁻ᵃ = 1/xᵃ

It is given that, (2⁵)⁻²

<u>To find the equivalent of (2⁵)⁻²</u>

(2⁵)⁻² =  2⁻¹⁰

<u>To find the value of 2⁻¹⁰</u>

2⁻¹⁰ = 1/2¹⁰

2¹⁰ = 1024

1/2¹⁰ = 1/1024

Therefore the correct answer is 3rd option

2⁻¹⁰ and 1/1024

Find the missing part.
sveta [45]

Answer:

The answer is a = \frac{15}{4}

Step-by-step explanation:

We have to:

cos(\theta) = \frac{adjacent\ side}{hypotenuse}

So, if we take the 60 degree angle of the smallest triangle, we have to:

cos(60) = \frac{a}{x}

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

sin(30) = \frac{x}{15}\\\\x =\frac{15}{2}

Then:

cos(60) = \frac{a}{\frac{15}{2}}

a = cos(60)\frac{15}{2}

a = \frac{15}{4}
