Q. Evaluate the following expression.\newline40⋅8−102= 40 \cdot 8-10^{2}=
  1. Evaluate multiplication: Evaluate the multiplication part of the expression.\newlineThe expression is 40×8−10240 \times 8 - 10^{2}. We start by evaluating the multiplication part, which is 40×840 \times 8.\newlineCalculation: 40×8=32040 \times 8 = 320
  2. Evaluate exponentiation: Evaluate the exponentiation part of the expression.\newlineNext, we evaluate the exponentiation part, which is 10210^{2}.\newlineCalculation: 102=10×10=10010^{2} = 10 \times 10 = 100
  3. Subtract results: Subtract the result of the exponentiation from the result of the multiplication.\newlineNow we subtract the result of step 22 from the result of step 11.\newlineCalculation: 320−100=220320 - 100 = 220
