(a) Write 7.97 × 10-6 as an ordinary number. (b) Work out the value of (2.52 × 105) ÷ (4 × 10-3) Give your answer in standard form. How would I answer this? I'm really worried for my exams

(a) Write 7.97 × 10-6 as an ordinary number =0.00000797.

 

(b) Work out the value of (2.52 × 10^5) ÷ (4 × 10^-3) Give your answer in standard form

(2.52 × 10^5) ÷ (4 × 10^-3) =252000 / 0.004 =63,000,000.
