Answer:

Step 3 is wrong and the answer should be 576

Step-by-step explanation:

Step 1 and step 2 are correct

Step 2: 4 × 12^2

You don't multiply 12 by 4, you first complete the exponent since, in PEMDAS, Exponent is before Multiplying.

Step 3 should be: 4 × (12×12)

= 4 × 144

= 576

42/40 into a mixed number is??

SSSSS [86.1K]

Hello there!

So, as we see that 42 is more than the denominator, so, we would have to see by how much it would be over.

40-42=2.

So, sense we have an whole number which would be (1)

Your answer: $\boxed{\boxed{\bf 1\frac{2}{40} }}$
