I is -8x^2.
x2*x2...You would add the two exponents like this x(2+2), making it x4.
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
x^2+2x^2=3x^2
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 squared
(x squared plus the square root of 2) times (x squared minus the square root of 2).
