Planet A is at a distance of 9 . 35 × 10 6 km from earth and planet B is 6 . 27 × 10 7 km from earth. Which planet is nearer to earth?

The large numbers are written in standard form as N × 10 n , where N is the number between 1 and 10 and n is the power of 10 . To compare two numbers written in standard form, first compare the exponents of 10 . The number with the larger exponent is larger. If the exponents of 10 (the value of n ) are equal, then compare the coefficients (the value of N ) Given that the planet A is at a distance of 9 . 35 × 10 6 km from earth and the planet B is 6 . 27 × 10 7 km from earth. Here, both distances are in standard form. We observe that the distance 6 . 27 × 10 7 km has larger exponent than the distance 9 . 35 × 10 6 km . Therefore, the planet is nearer to the earth.
