Which expression is equivalent to (3 squared) Superscript negative 2? –81 –12 StartFraction 1 Over 81 EndFraction One-twelfth
KonstantinChe [14]

Answer:

The correct option is:

1/81

Step-by-step explanation:

The given expression to us is:

(3²)⁻²

In this expression, the two powers, which are 2 and -2, are multiplying with each other, we can write it as:

(3)⁻⁴

Now we know that a negative power of a number can be converted into a positive power one if we take reciprocal of the given number.

It can be written as:

(1/3)⁴

Further simplify the expression:

1/81

Thus the correct choice from the given options is:

1 over 81 or 1/81

Please find the solution set of x+3>19-3x, where x is a real number​
belka [17]

Answer:

x >4

Step-by-step explanation:

x+3>19-3x

Add 3x and -3 on both parts.

x+3+3x-3>19-3x+3x-3

Combine like terms.

x+3x>16

4x >16

Divide 4 on both parts.

\frac{4x}{4} > \frac{16}{4}

x >4

Find the value of x in the isosceles triangle shown below.
guajiro [1.7K]

Answer:

B) x = \sqrt{60}

Step-by-step explanation:

1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.

2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: a^2 + b^2 = c^2, where a = height, b = base, and c= hypotenuse.

  • a^2 + 2^2 = 8^2
  • a^2 + (2*2) = (8*8)
  • a^2 + 4 = 64 (Simplify both sides of the equation)
  • a^2 + 4 - 4 = 64 - 4 (Subtract 4 from both sides)
  • a^2 = 60
  • \sqrt{a^2} = \sqrt{60} (Take square root of both sides
  • a = \sqrt{60}

3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.
