## ACT Question of the Day

The ACT question for today asks how you would represent an x that is multiplied by itself four times. This should be an easy question if you understand exponents. Think about it: (x)(x)(x)(x) contains x four different times. You write this in math as x to the power of 4. Remember, an exponent is just a short way to write how many times you are multiplying a number by itself. If you find exponents difficult, you can still reach the answer by using the strategy of choosing a number for x and seeing which answer choice matches the original problem.
Look at the answer choices on the ACT site.

(A) Is meant to distract you if you see x four times and think of multiplication. However, try plugging in x = 1. (1)(1)(1)(1) = 1, but 4(1) = 4. This answer cannot be correct.

(B) This answer matches your answer! It also works if you plug in x = 1. (1)(1)(1)(1) = 1 and 1

(C) If you plug in x = 1, you will see that this answer is incorrect. (1)(1)(1)(1) = 1, but 1 + 4 = 5.

(D) Again, if you aren’t sure, plug in x = 1. (1)(1)(1)(1) = 1, but 4

(E) This answer is also incorrect. (1)(1)(1)(1) = 1, but 2(1)

(A) Is meant to distract you if you see x four times and think of multiplication. However, try plugging in x = 1. (1)(1)(1)(1) = 1, but 4(1) = 4. This answer cannot be correct.

(B) This answer matches your answer! It also works if you plug in x = 1. (1)(1)(1)(1) = 1 and 1

^{4}=1.(C) If you plug in x = 1, you will see that this answer is incorrect. (1)(1)(1)(1) = 1, but 1 + 4 = 5.

(D) Again, if you aren’t sure, plug in x = 1. (1)(1)(1)(1) = 1, but 4

^{1}= 4. This does not match your original equation.(E) This answer is also incorrect. (1)(1)(1)(1) = 1, but 2(1)

^{2}= 2.The correct answer is (B).
