Answer :

Certainly! Let's simplify the given expression step-by-step:

The given expression is:
[tex]\[ \left(3^2\right)\left[(4-2)^3-\left(2+1^0\right)\right] \][/tex]

1. Simplify the first part inside the parentheses:
- Calculate [tex]\(3^2\)[/tex]:
[tex]\[ 3^2 = 9 \][/tex]

2. Simplify the second part inside the outer brackets:
- First, handle the expression [tex]\((4-2)\)[/tex]:
[tex]\[ 4 - 2 = 2 \][/tex]
- Then, raise this result to the power of 3:
[tex]\[ 2^3 = 8 \][/tex]

3. Simplify the expression inside the second set of parentheses:
- Evaluate the power inside the parentheses:
[tex]\[ 1^0 = 1 \][/tex]
- Then, add it to 2:
[tex]\[ 2 + 1 = 3 \][/tex]

4. Subtract the results obtained in steps 2 and 3:
- Subtract the value obtained in step 3 from the value in step 2:
[tex]\[ 8 - 3 = 5 \][/tex]

5. Multiply the result from step 1 by the result from step 4:
- Multiply [tex]\(9\)[/tex] by [tex]\(5\)[/tex]:
[tex]\[ 9 \times 5 = 45 \][/tex]

Thus, the simplified expression is:
[tex]\[ 45 \][/tex]

In summary:
[tex]\[ \left(3^2\right)\left[(4-2)^3-\left(2+1^0\right)\right] = \left(9\right)\left[8-3\right] = 45 \][/tex]
