x = -3
4x to the 3rd power -4x to the 2nd power -43 when x=3
6 to the -2nd power = 1/366-2 = 1/62 = 1/36
The GCF is x2
A negative power equals the reciprocal of the same number to the equivalent positive power. Example : 2 ⁻³ = 1/2³ Then 8⁻² = 1/8² = 1/64 = 0.015625
x = -3
The number 7 raised to the 2nd power (or squared) equals 49.
1.5 to the 2nd power equals 2.25
Seven to the 2nd power equals 49
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
18 to the 2nd power is 324. To solve you just take 18 and times it by 18. It is the same with any power problem.
a, a^3*a^-2 is a^3+-2 which equals just a

An equation.
5 over 8 to the negative 2nd power equals 2.56
