It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.
No it is not.
x to the third power plus 7
-7p2 -2p3 + 5 is an expression, not an equation or inequality. An expression cannot be solved
x3 + 3x + 5x + 15That's a third-degree expression in 'x'.It can be cleaned up a little bit, by adding the 3x and the 5x. Doing thatdoesn't change anything; it only makes the expression neater:x3 + 8x + 15Now it's a third-degree trinomial in 'x'. If anybody wants to know what numberthe expression is equal to, they'll have to tell you what number 'x' is first. Thevalue of the whole expression depends on the value of 'x', and every time 'x'changes, the value of the expression changes.Notice that it's not an equation, it doesn't ask any question, and it has nosolution or 'answer'. It's just a number, the value of which can be anything.
The verbal expression of 3b to the second power plus 2a to the 3rd power is "three b squared plus two a cubed."
x3 + 5x2 + 2x - 8It's a third-order polynomial in 'x'.Its value depends entirely on the value of 'x', and whenever 'x' changes,the value of the whole polynomial instantly changes.
++ is an operator that increments the operand. The value of the operand in the expression is incremented first if the ++ is before the operand. The value of the operand in the expression is the same value if the ++ is after the operand.
It's 32 + 24
It is 25.
