Take the log or natural log of both sides ln7x=9573 one of the laws allows to move the exponent in front xln7=9573 solve for x 9573/ln7 = x x is approximately 4919.54 Added info by qadzbork: I think there is a misplaced decimal above as 7 to the fifth power is more than 9573. 7 to the fourth is 2401, so it may be that the answer is 4.91954.

7 X 7 X 7 equals "seven to the third power" or "seven cubed".
e3x+5 x ex =7 e3x+5+x=7 4x+5=ln(7) x=(ln(7)-5)/4
Twenty to the negative 5th power equals 3.125e-7 or 3.125 x 10-7
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
Reflexivity is a property of equality, i.e., X = X is always true. Thus -7 raised to the power of 3 equals -7 raised to the power of 3 is true.

7 X 7 X 7 equals "seven to the third power" or "seven cubed".
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
seven 7 x 7 x 7 = 49 x 7 = 63 + 280 = 343 = 7³
e3x+5 x ex =7 e3x+5+x=7 4x+5=ln(7) x=(ln(7)-5)/4
x = 14
Twenty to the negative 5th power equals 3.125e-7 or 3.125 x 10-7
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
Seven to the 7th power, written as 7^7, is equal to 7 multiplied by itself 7 times. This results in 7 x 7 x 7 x 7 x 7 x 7 x 7, which equals 823,543. In mathematical terms, raising a number to a power means multiplying the base number by itself the number of times indicated by the exponent.

-7+x=13x the -7=12x and x =-7/12
