What is the value of the expression below? (9^2) ^1/4
Gennadij [26K]

Answer:

3

Step-by-step explanation:

1. Note that 9=3^2.

2. Use property (a^m)^n=a^{m\cdot n}, then

9^2=(3^2)^2=3^{2\cdot 2}=3^4.

3. Use the same property, thus

(9^2)^{\frac{1}{4}}=(3^4)^{\frac{1}{4}}=3^{4\cdot \frac{1}{4}}=3^1=3.

Have to find the side length of x for the following right triangle?<br>​
nasty-shy [4]

Answer:

x = 9

Step-by-step explanation:

<h3> Pythagorean theorem:</h3>

     \sf (leg_1)^2  + (leg_2)^2 = hypotenuse^2

                x^{2} + 12^2 = 15^2\\\\x^{2} + 144  = 225

                          x²  = 225 - 144

                          x²  = 81

                          x² = 9²

                         x = 9

                          \boxed{x = 9}
