1 answer

Let's evaluate the expression 12(970)+(29)0.

  1. First, we calculate 70 and (29)0:

    • Any non-zero number raised to the power of 0 equals 1, so:
      • 70=1
      • (29)0=1
  2. Now substitute these values back into the expression: 12(91)+1

  3. Simplify the expression inside the parentheses: 91=8

  4. Multiply: 12×8=96

  5. Finally, add: 96+1=97

Now, let's examine the answer choices given:

  1. 12(2)+1: Evaluates to 24+1=25 (not equivalent)
  2. 12(90)+0: Evaluates to 12×9+0=108+0=108 (not equivalent)
  3. 12(91)+1: Evaluates to 12×8+1=96+1=97 (this is equivalent)
  4. 12(91)1: Evaluates to 12×81=961=95 (not equivalent)

The equivalent expression to 12(970)+(29)0 is: 12(91)+1.
