1.945*10^10 and yes your polynomial is correct.
I am sorry, your scientific notation is correct. When moving decimal to left exponent is positive.
your first answer is right except the second term which should be 5x^3. And writing in scientific notation, when moving decimal to left, exponent is negative, so correct answer will be 1.945*10^-10
when it is positive exponent you move decimal point to the right by that number. so in this case move decimal to right by 11 places so answer should be 883,000,000,000
The first two terms are correct in your answer but the exponent for last term is wrong. When you are multiplying the exponents are added. So t^2.t^3 = t^(2+3) = t^5 so answer will be: 8t^3 - 8t^4 + 56t^5
You move decimal place after first significant figure and number of places you move does become your exponent but when you move right, exponent is negative and when you move left exponent is positive. Since in this case we are moving decimal to right by 10
No the answer should have 10 zeros. When you multiply two same numbers their exponents are added. so 10^6.10^4 = 10^(6+4). when it is like this (10^6)^4 then you multiply exponents and get 10^24. so answer is 60,000,000,000
