Simplify: ((-3)4)².
Darina [25.2K]

The value of the expression ((-3)^4)^2 when simplified is 6561

<h3>What are expressions?</h3>

Expressions are mathematical statements represented by numbers, arithmetic operations and variables

<h3>How to simplify the expression?</h3>

The expression is given as:

((-3)^4)^2

Start by expanding the inner bracket

((-3)^4)^2 = ((-3)*(-3)*(-3)*(-3))^2

Next, we evaluate the product (-3)*(-3)*(-3)*(-3)

This gives

((-3)^4)^2 = (81)^2

Next, expand the exponent

((-3)^4)^2 = (81) * 81

Next, we evaluate the product

This gives

((-3)^4)^2 = 6561

Hence, the value of the expression ((-3)^4)^2 when simplified is 6561
