r - 13/6 = ( 7r - 3/2 ) - ( 2/3 + 6r )

13r + 20 = ( 6r + 7 ) + ( 13 + 7r )

-12 + r = ( -8 - r ) + ( 2r - 4 )

What is the value of Left-bracket (two-thirds) Superscript 0 Baseline Right-bracket Superscript negative 3?
Vinil7 [7]

Answer:

The value of the expression is 1.

Step-by-step explanation:

The expression is:

[(\frac{2}{3})^{0}]^{-3}

Exponent rules:

a^{0}=1\\\\(a^{m})^{n}=a^{m\times n}\\\\a^{-m}=\frac{1}{a^{m}}

Simplify the expressions as follows:

[(\frac{2}{3})^{0}]^{-3}=[1]^{-3}

            =\frac{1}{1^{3}}\\\\=\frac{1}{1}\\\\=1

Thus, the value of the expression is 1.
