The given expression is 4^{3} \times 4^{x}

By using the law of exponent which states that a^{m} \times a^{n} = a^{m+n}

4^{3} \times 4^{x} = 4^{3+x}

We need to find the equivalent expression for the given expression from the given expressions.

1. 4^{3} \times 4^{x} = 4^{3+x}

This expression is equivalent to the given expression.

2. (4 \times x)^{3} = (4x)^{3} = 64x^{3}

This expression is not equivalent to the given expression.

3. 4^{3-x}

This expression is not equivalent to the given expression.

4. 64 \times 4^{x} = (4)^{3} \times 4^{x}=4^{3+x}

This expression is equivalent to the given expression.

5. 4^{3x}

This expression is not equivalent to the given expression.

6. 16^{3x}=(4^{2})^{3x}=4^{6x}

This expression is not equivalent to the given expression.

wolverine [178]

According to the given percentages, it is found that there is a 67% probability that a randomly selected man between the age of 25 and 34 does not search for green technology.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

We have that 33% of men search for green technology, hence, there is a 100 - 33 = 67% probability that a randomly selected man between the age of 25 and 34 does not search for green technology.

erica [24]

Answer:

x=6, x= -5

Step-by-step explanation:

Factor the equation

x^2 - x - 30 = 0 ----> (x-6)(x+5)=0

Next find the solution by setting those in the paranthesis equal to zero.

x-6=0 ----> x= 6

x+5=0 ----> x= -5
