Which expression is equivalent to (4(5^3)1/2?
Feliz [49]

Answer:

10\sqrt{5}

Step-by-step explanation:

In this problem, we are given expression in exponent form and we have to simplify the expression.

The expression is [4(5^{3} )]^{\frac{1}{2} }

Now, we know that 5^{3} = 5 \times 5 \times 5 = 125

So, 4(5^{3} ) = 4 \times 125 = 500

Now, 500 can be written as 100 × 5 = 10² × 5

Therefore, [4(5^{3} )]^{\frac{1}{2} } = (500)^{\frac{1}{2} } = 10\sqrt{5} {Since 500 = 100 × 5 = 10² × 5} (Answer)

Step-by-step explanation:

If 6 numbers have a mean value of 10, it means that the sum of the numbers divided 6 is equal to 10. This can be expressed as:

x÷6=10

x=60

The new number added will be the 7th number and now the mean is 9. You have to ask what number divided by 7 is equal to 9? This can be expressed as:

y÷7=9

y=63

63-60=3

So the new number added is 3
