Ok so i know how to multiply in scientific notation but this one is so hard. pls help and PLS show your work.
juin [17]
Basically if you have an exponent at the end of a 10, 10^{7} , then in the end the extended notation is going to have 7 zeros. So it'll be 10000000. Then you multiply whats in the rest of the equation together. There's the beginning :) I hope it helps.

It cost benjamin 1.35 to send 9 text messages. How much would it cost to send 118 text messages?
Hatshy [7]

price of one message = 1.35 ÷ 9

1.35 ÷ 9 = 0.15

0.15 • 118 = ( 3 ÷ 20 ) • 118

118 • 3 = 354

354 ÷ 20 = 177 ÷ 10 = $17.7 to send 118 messages

Please help to solve this<br>Find H.C.F <br>m^3 - 1, m^4 + m^2 + 1, m^2+ m + 1​
Nikitich [7]

Answer:

m^2+m+1

Step-by-step explanation:

  • m^3 - 1= (m-1)(m^2+m+1)
  • m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
  • m^2+ m + 1​

HCF= m^2+m+1 which is the factor of all three polynomials
