Answer:

(8^{\frac{2}{3} } )^{4} = 256

Step-by-step explanation:

Given

(8^{\frac{2}{3} } )^{4}

Required

Simplify

To simplify this, we apply law of indices but first we start by solving the expression in bracket.

8 =2 * 2 * 2

8 = 2³

So, we substitute 2³ for 8

(8^{\frac{2}{3} } )^{4} becomes

((2^{3})^{\frac{2}{3} } )^{4}

From law of indices

a^{n} = (a^{m})^{\frac{n}{m} } ==> (a^{m})^{\frac{n}{m} } = a^{n}

So, (2^{3})^{\frac{2}{3} } = 2^{2}

At this point we have

((2^{3})^{\frac{2}{3} } )^{4} = (2^{2})^{4}

Also, from law of indices

(a^{m})^{n} = a^{m.n}

So,

((2^{3})^{\frac{2}{3} } )^{4} = (2^{2})^{4}

(2^{2})^{4} = 2^{2*4}

(2^{2})^{4} = 2^{8}

(2^{2})^{4} = 256

Hence,

(8^{\frac{2}{3} } )^{4} = 256

Solve the following two equations. Show all of your
Harrizon [31]
Equation 2:
3(18 - 3) = 45
step 1 do 18-3
now you have
3(15) = 45
and it’s just three, times fifteen.
3 • 15 = 45

Equation 1:
3x + 11 = 11
3x = 11 - 11
3x = 0 (divide both sides by 3 to get x)
3x/3 = 0/3
x = 0
