X + (x+2) = 154
combine like terms
2x + 2 = 154
subtract 2
2x = 154
divide by 2
x = 76
so the two numbers are 76 and 78
Hi!
-2x³ + 5x - 7 = -2 * (-3)³ + 5 * (-3) - 7 =

When multiplying exponents it’s quite simple
(x)(x)= x^2
(x^3)(x^3)= x^6
Raising a function with an exponent with another exponent
(x^4)^4 is x^16
So when two functions to a power are multiplied the exponents add. Then a function with an exponent is raised to another exponent, the exponents multiply.
