Answer:
um read below
Step-by-step explanation:
so, lets go to the first parentheses. 2.53 x 10. To multiply a decimal by 10, move the decimal point to the right by 1 place. that equal 25.3. Oh wait do I see a -5 exponent tho- if it is, 10 exponent -5 is 1/100,000. to multiply, it would equal 2.53/100000. which equals 0.0000253
the second parentheses now. 10 exponent 0 is the same as 1. any exponent of 0 is going to equal 1. so 4 x 1 = 4.
multiply em now! 4 x 2.53/100000 = 0.0001012. um transform to simplest form is uh u can search it up sry, and scientific notation dk so uh hope could help in the most calculation part. :)
