I is -8x^2.
x2*x2...You would add the two exponents like this x(2+2), making it x4.
(2x)2(x) = 4x3
x to the power of 2 is equal to x times x (x squared). This is written as x2.
We know that when you submit questions you aren't free to use the right format to make the mathematical terms crystal clear. It is likely that you mean "x squared times 6 plus x squared times 2", which is clearer. You can factor out the "x squared" and you will see that you get "x squared times 8". You COULD mean (6x) squared plus (2x) squared, which would be different. 6x times 6x would equal x squared times 36, so your answer will be much different.
If you mean -(x^2) * x then the answer is -x^3 if you mean (-x)^2 * x then the answer is x^3
2 times 2 times 2 times x times x = 8x2
Why don't you figure it out yourself
No. x squared is x times x, whereas 2x is x + x.
x times x equals x^2, or x squared.
5(x^2 + y)
I is -8x^2.
x2*x2...You would add the two exponents like this x(2+2), making it x4.
3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
Answer 1 Put simply, sine squared is sinX x sinX. However, sine is a function, so the real question must be 'what is sinx squared' or 'what is sin squared x': 'Sin(x) squared' would be sin(x^2), i.e. the 'x' is squared before performing the function sin. 'Sin squared x' would be sin^2(x) i.e. sin squared times sin squared: sin(x) x sin(x). This can also be written as (sinx)^2 but means exactly the same. Answer 2 Sine squared is sin^2(x). If the power was placed like this sin(x)^2, then the X is what is being squared. If it's sin^2(x) it's telling you they want sin(x) times sin(x).
4x^2
(x squared plus the square root of 2) times (x squared minus the square root of 2).
