Question

Answer expression 1:

6 x 7 - 3^2 x 9 + 4^3

Answer 1

The value of the expression is 25.

Explanation:

Consider the provided expression.

`6 * 7 - 3^2 * 9 + 4^3`

First simplify the exponents.

`3^2=9\ and\ 4^3=64`

Substitute the value of exponents in the provided expression.

`6 * 7 - 9 * 9 + 64`

`42- 81+ 64`

`106- 81`

`25`

Hence, the value of the expression is 25.

Answer 2

In order to get the answer to this question you will have to use PEMDAS and solve.

`6*7-3^2*9+4^3`

Using PEMDAS:

`3^2=3*3=9`

`4^3=4*4*4=64`

`6*7-9*9+64`

`6*7=42`

`9*9=81`

`42-81+64`

`81+64=145`

`42-145`

`42-145=-103`

`=-103`

Therefore your answer is "-103."

Hope this helps.
