Question

7×10³–2.4×10² give answer in standard form

Answer 1

To subtract two numbers in scientific notation, subtract the coefficients and keep the exponent the same. The answer in standard form is 4.6 × 10³.

Step-by-step explanation:

To subtract two numbers in scientific notation, we need to make sure the exponents are the same. In this case, both numbers are already in scientific notation and have the same exponent of 3, so we can directly subtract the coefficients: 7 - 2.4 = 4.6. The answer in standard form is 4.6 × 10³.
