Answer
$9.3 \times 10^{7}$
$5.3 \times 10^{-23}$
$5.97 \times 10^{24}$
Work Step by Step
93 Million = 93,000,000
Move the decimal point over 7 spaces makes the exponent $10^{7}$ thus $9.3 \times 10^{7}$
0.000000000000000000000053
Moving the decimal point to the right makes the exponent negative. Move it 23 times and you get $5.3\times10^{-23}$
5,970,000,000,000,000,000,000,000
Move the decimal point over 24 spaces makes the exponent $10^{24}$ thus $5.97 \times 10^{7}$
