Which of the following is equivalent to (x^4/3 x^2/3)^1/3

Reika [66]

Answer:

The answer is2nd point

Step-by-step explanation:

${n}^{a} \times {n}^{b} = {n}^{a + b}$

(x^4/3)×(x^2/3) = x^(4/3 + 2/3)

= x²

${( {n}^{a} )}^{b} = {n}^{ab}$

(x²)^1/3 = x^(2×1/3)

= x^2/3

If angle pqt is (3x+47)and angle sqr is (6x-25), find the measure of angle sqr

Radda [10]

Answer:

Angle sqr = 119°

Step-by-step explanation:

In the above question, we are given:

angle pqt is (3x+47)°

angle sqr is (6x-25)°

Angle pqt = Angle sat

We solve for x

3x + 47 = 6x - 25

Collect like terms

47 + 25 = 6x - 3x

72 = 3x

x = 72/3

x = 24

We solve for the measure of angle sqr

Angle sqr = (6x - 25)

x = 24

6 × 24 - 25

144 - 25

= 119°
