Anwer:

14 cm

Step-by-step explanation:

Let's apply the Phytagorean Theorem $a^{2}+b^{2}=c^{2}$

Since we only have one side and the hypotenuse:

$a^{2}+24^{2}=28^{2}\\a^{2}+576=784\\a^{2}=784-576\\a^{2}= 208\\$

$a=\sqrt{208}\\a= 14.42\\a= 14 cm$

To solve this you will need to know the Pythagorean therum A^2+B^2=C^2

24^+B^2=28^2
576+B^2=784
-576. -576
B^2=208
Square root of 208 is about 14.42 and that is the length of the wall

Equivalent answers for 64 to the power of 2/3

madreJ [45]

Answer:

Step-by-step explanation:

Dealing with a fraction exponent on hand can be converted by using the fractional exponents rule where the fraction exponent is converted to something like this:

$64^\frac{2}{3} = \sqrt[3]{64^{2}}\\$

As you can see, the denominator of the fractional exponent is now the index of the radical. Here is a guide to know what goes where.

$64^\frac{x}{y} = \sqrt[y]{64^{x}}$

Both the original problem (64^2/3) and the converted formula can be put into a calculator.

Simplify (if you want to)

$\sqrt[3]{64^{2}}\\\sqrt[3]{4096}\\16$

64 to the power of 2/3 is 16.
