Answer:

Step-by-step explanation: (8a + 2b + -4) = (3b + -5)

Reorder the terms:

(-4 + 8a + 2b) = (3b + -5)

Remove parenthesis around (-4 + 8a + 2b)

-4 + 8a + 2b = (3b + -5)

Reorder the terms:

-4 + 8a + 2b = (-5 + 3b)

Remove parenthesis around (-5 + 3b)

-4 + 8a + 2b = -5 + 3b

Solving

-4 + 8a + 2b = -5 + 3b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 8a + 4 + 2b = -5 + 4 + 3b

Reorder the terms:

-4 + 4 + 8a + 2b = -5 + 4 + 3b

Combine like terms: -4 + 4 = 0

0 + 8a + 2b = -5 + 4 + 3b

8a + 2b = -5 + 4 + 3b

Combine like terms: -5 + 4 = -1

8a + 2b = -1 + 3b

Add '-2b' to each side of the equation.

8a + 2b + -2b = -1 + 3b + -2b

Combine like terms: 2b + -2b = 0

8a + 0 = -1 + 3b + -2b

8a = -1 + 3b + -2b

Combine like terms: 3b + -2b = 1b

8a = -1 + 1b

Divide each side by '8'.

a = -0.125 + 0.125b

Simplifying

a = -0.125 + 0.125b

Rewrite the expression with rational exponents as a radical expression by extending the properties of integer exponents.
ra1l [238]

The expression will be written as \rm \sqrt[8]{2^5}., the correct option is A.

<h3>What are Exponents?</h3>

Exponents are the base raised to a power, It is written in the superscript of a number.

The expression given in the statement can be written as

\rm \dfrac{ 2^{7/8}}{2^{1/4}}

By the Exponent rule,

\rm \dfrac{a^m}{a^n} = a^{m-n}

So the expression can be written as

<h3>=\rm { 2^{7/8-1/4}</h3>

=\rm 2^{5/8}

=\rm \sqrt[8]{2^5}

Therefore, in radical form, the expression will be written as \rm \sqrt[8]{2^5}., the correct option is A.

The complete question is

Rewrite the rational exponent as a radical by extending the properties of integer exponents.

2 to the 7 over 8 power, all over 2 to the 1 over 4 power

the eighth root of 2 to the fifth power

the fifth root of 2 to the eighth power

the square root of 2 to the 5 over 8 power

the fourth root of 2 to the sixth power
