Answer 9

The expression that is equivalent to (2x9)^4 is option A: 2^4 x 9^4.

To simplify (2x9)^4, we start by multiplying 2 and 9 together to get 18. So, we have (18)^4.

Then, we can use the rule that says (a^n)^m = a^(n*m) to simplify further. So, (18)^4 can be written as (2 x 9)^4, which is equivalent to 2^4 x 9^4.

Therefore, the correct answer is A: 2^4 x 9^4.

Answer 10

The expression that is equivalent to 5^x7^2 is option A: (5 x 7)^2.

To simplify 5^x7^2, we need to recognize that 5 and 7^2 (or 49) are two separate factors, with no common factor between them.

So, we can write 5^x7^2 as (5^x)(49).

Since 49 is a perfect square, we can simplify further to get (5^x)(7^2), which is equivalent to (5 x 7)^2.

Therefore, the correct answer is A: (5 x 7)^2.

Answer 11

To simplify (5 x 7)^2, we need to perform the multiplication inside the parentheses first, and then raise the result to the power of 2.

So, (5 x 7)^2 can be rewritten as (35)^2.

To simplify further, we can use the formula for (a)^2, which is a x a. Therefore, (35)^2 can be written as:

(35)^2 = 35 x 35

We can now multiply 35 by 35 to get the final answer:

(5 x 7)^2 = (35)^2 = 35 x 35 = 1225

Therefore, (5 x 7)^2 simplifies to 1225.

Answer 12

The expression that is equivalent to 3/2^3 is option C: 3/2.

To simplify 3/2^3, we need to evaluate the exponent first, which is 2^3 equals to 8, so 2^3 = 8.

Then we can replace 2^3 with 8 in the denominator:

3/2^3 = 3/8

So the simplified form of 3/2^3 is 3/8, which is equivalent to option C: 3/2.

Therefore, the correct answer is C: 3/2.

Answer 13

I apologize for the incorrect response earlier. The expression that is equivalent to 3/2^3 is option D: 3^3/2^2.

To simplify 3/2^3, we first evaluate the exponent 2^3, which is equal to 8. Then we can rewrite the expression as:

3/2^3 = 3/8

To simplify this fraction further, we can express 3 as 3^1 and 8 as 2^3. Then, using the rule that (a^m)/(a^n) = a^(m-n), we can rewrite 3/8 as:

3^1/2^3 = 3^(1-3)/2^3 = 3^(-2)/2^3

To eliminate the negative exponent, we can move it to the denominator by flipping the fraction:

3/2^3 = 3^2/2^3 x 1/3^2 = 9/2^3 = 9/8

Therefore, the correct answer is D, 3^3/2^2.
