2 to the third power is 2³
so 2 to the third power times -5 is 2³ * (-5)
which on simplification will be 8* (-5) =-40
I don't understand your question, expressions do not end with equal signs. Or are you just asking how to write the expression?
2*((3*x)^3)+2(y^2) then simply replace the x with "-2" and y with "sqrt(12)"
2*(-2)^3+2(12)
-16+24
8
Answer:
1 * 10^12
Step-by-step explanation:
Scientific notation is a representation of a large number in a short form. The answer, 1*10^12 (read as ten to the twelfth power) essentially says that the number when expanded is 1 with 12 zeros appended to it. If you did a number like 7 trillion you would have 7 * 10^12.
Same thing can be applied for 1,000,000 (one million).
1 * 10^6 because one million has 6 zeros appended to it.
