Question

Please solve I do not understand it

Answer 1

The expression $(\frac{1}{4^{-3 } } )^{-2}$ is less than 1.

The sign to change to make the expression greater than 1 is changing the sign of the exponential value which will make the new expression as

$(\frac{1}{4^{-3 } } )^{2}$

What is expression?

In maths, an expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.).

In other words, an algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.)

Therefore, let's simplify the expression to know if it's equals to 1, greater than 1 or less than 1.

$(\frac{1}{4^{-3 } } )^{-2}$

using law of indices,

$(\frac{1}{4^{-3 } } )^{-2}$ = 1 × $(4^{-3} )^{2}$

4⁻⁶  = 1 / 4⁶ = 1 / 4096

Hence,

1 / 4096 = 0.00024414062

Therefore,  the value is less than 1.

Let's change one sign to make the expression greater than 1.

Therefore, the expression will be $(\frac{1}{4^{-3 } } )^{2}$
