According to the rule of BODMAS multiplication goes first.
B - brackets O - operations D - division M - multiplication A - addition S - subtraction
to answer the question, 4 ^ x goes first. which equals 4x. the new equation would be: 4x + 3 = 18 now you have to move +3 over the equals sign which becomes negative (-): 4x = 18 - 3 4x = 15 next you have to get the x to be alone, move the 4 over the equals sign. 15 is now divided by 4: x = 15/4 x = 3.75
