Answer:
-99232
Explanation:
PEMDAS
Solve in the brackets/parenthesis and expand out
4*9=36*3=108-12=96
Now we have (96)*8-10^5
Next up is exponents so -10^5 is -100000
Next is multiplication so (96)*8=768
Lastly is subtraction: 768-100000= -99232
Scientific notation of this answer is -9.9232*10^4 (depends which answer they are looking for)
