Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:
Small numbers:
However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
Answer:
17,250
Step-by-step explanation:
since there are 1000 grams for each kilogram
Answer:
your answer will be option A
Step-by-step explanation:
(8w^7x^-5y^3z^-9)-2/3
= (8)-2/3×(w^7)^-2/3×(x^-5)^-2/3×(y^3)^-2/3×(z^-9)-2/3
=(2^3)^-2/3×w^-14/3×x^10/3
xy^-2xz^6
=2^-2 w^-14/3 x^10/3 y^-2 xz^6
=1/4×1/w^14/3× x^10/3 xz^6/y^2
=x^10/3z^6/4w14/3y^2
hope it helps..
have a great day!!
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.
-10u^3-16u^2*4u is the answer
