What is the base of the exponential expression 43?
Explanation
In the exponential expression 4^3, the number 4 is referred to as the base. The base represents the number that is repeatedly multiplied by itself a certain number of times, indicated by the exponent. In this case, the base 4 is multiplied by itself three times because the exponent is 3. So, 4^3 means 4×4×4, where 4 is multiplied by itself three times.Rate this question:

Solve: (23)2
Explanation
To solve (2^3)^2, we need to apply the power of a power rule, which states that (x^m)^n = x^(m*n)
Therefore, (2^3)^2 = 2^(3*2) = 2^6 = 64Rate this question:

(3)-2
Explanation
The value of (3-2) can be found by taking the reciprocal of 32, which is (1/32).
(32) equals (3 x 3 = 9).
So, 3-2 = 1/32 = 1/9
Therefore, 3-2 equals 1/9Rate this question:

(a2b)3 = a5b3
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement (a2b)3 = a5b3 is not true. In order to simplify the expression (a2b)3, we need to multiply the exponents inside the parentheses by the exponent outside the parentheses. This gives us a6b3. Therefore, the correct answer is False.Rate this question:
