Answer:

1.75 10^-15 scientific notation

Step-by-step explanation:

(2.5×10^−10 = 0.00000000025) *  (7 ×10^−6 = 0.000007 ) =1.75 10^-15 = 0.0000000000000015 we just count 15 zeros from decimal at 1.5 back 15 spaces place the decimal and add another zero in front of the decimal or do the multiplication 2.5* 7 = 1.75   and 1.75 *100 (^-10 -^6 ) =1.75 *100 --^16 -10 shown fro the 100 preceding  = .75 *100 --^16 -10  = .75 *100 --^15 or just do 0.000007 * 0.00000000025 = 0.0000000000000015  as -700 * -25 = 17500 and as this is moved (a to b) by 4 places we can place decimal back 4 places to get 0.0000000000000015   decimal notation
