No the correct answer 18
Order of operations says you must MULTIPLY before you ADD.
so it's 3x5 = 15 then 15+3 = 18

First let’s make sure that you know how to use the keyboard for equations (algebra and Mathematics).
When you type “5X3”, I assume you mean 5 times X to the power of 3. In that case you need to type like this: 5(X^3).
The way you have typed, the term of “5X3”,does not make sense and only cleats confusion for those willing to help you.
Having said that:
3 + 5(X^3)
5(X^3) = -3
X^3 = -3/5
X = (-3/5)^1/3
Solve it for X.
X = 0.7214
==============================================
However, if by typing “5X3”, you mean 5 multiply by 3, then:
3 + 5X3 = 3 + (5 X 3) = 3 + 15 = 18
=============================================
Some general info about keyboard:
^ Means Power
* Means Multiply
- Means Minus
+ Means Sum
/ Means Divide

3+5x3 = 3 + 15 = 18

Order of operations makes 3+5x3 the same as 3+(5x3). 5x3 is 15, so it's the same as 3+15. 3 + 15 is 18.
So the answer is 18.

The answer is 18.
To get the answer..you do mutiplication first which is 5x3. Now you have 3+15...which equals 18.

According to order of operations you multiple before you ad, so it would be 18 = (5*3) + 3.
