Certainly! Let's solve the expression step by step: [tex]\[\left[48(72-12)-15^2\right] \div 9\][/tex]
1. Calculate the inner expression [tex]\( 72 - 12 \)[/tex]:
[tex]\[
72 - 12 = 60
\][/tex]
2. Multiply the result by 48:
[tex]\[
48 \times 60 = 2880
\][/tex]
3. Calculate [tex]\( 15^2 \)[/tex]:
[tex]\[
15^2 = 225
\][/tex]
4. Subtract [tex]\( 15^2 \)[/tex] from the product of [tex]\( 48 \times (72-12) \)[/tex]:
[tex]\[
2880 - 225 = 2655
\][/tex]
5. Divide the result by 9:
[tex]\[
2655 \div 9 = 295
\][/tex]
Therefore, the final result of the expression [tex]\(\left[48(72-12)-15^2\right] \div 9\)[/tex] is
[tex]\[
295.0
\][/tex]
This is the answer: 295.0.
